[winswitch] Xpra GL and gtkglext woes

Post by Ben Sferrazza via shifter-users
Hi. I've built Xpra 2.2.4 on a Linux server at work which runs an old
distribution, CentOS 5. The kernel is 2.6.18, but I've created a fully
bootstrapped toolchain/binary/library environment that runs the latest
version of glibc (2.19) for the kernel, gcc 7.3.0, and binutils 2.30,
following most of the Linux From Scratch book. Everything I've thrown at it
works well, even having built Xorg, GTK+2/3, and GUI applications. I made
sure to build all the Xpra dependencies and built it with
--prefix=/home/tools, which is where my updated environment is.

Impressive!

I am considering using a similar approach (maybe using snap / flatpack /
appimage) to continue to support CentOS 6 in the future.

I have built Mesa, and am using the Xdummy xorg.conf. All seems well, but
the Xpra client never showed the --start-child app of konsole. It had
errors like this.
2018-03-05 17:04:40,440 x_event_filter event=('xpra-create-event',
None)/CreateNotify window=0x299

XError: XError: 3
2018-03-05 17:04:40,442 Some window in our event disappeared before we
could handle the event 16/CreateNotify using ('xpra-create-event', None);
so I'm just ignoring it instead. python event=<X11:CreateNotify
{'delivered_to': '0x299', 'send_event': 0, 'serial': '0x36a', 'type': 16,
'display': ':100'}>

Error 3 is BadWindow. This usually means that the window got destroyed
before we could get hold of it. (X11 is asynchronous)
I assume that you got this error in your server log with some debug
flags enabled, right?

So I then went ahead and installed gtkglext and the Python bindings,
thinking it was somehow related to OpenGL.

What makes you think that?
What vfb are you using? Are you using Xdummy or Xvfb? Have you tried
switching to the other option? Does your vfb support opengl?
Is using VirtualGL an option?
(there's quite a bit on the wiki about all these options)

Post by Ben Sferrazza via shifter-users
However, passing --opengl=no on
the command line when starting xpra appeared to do nothing.

Correct, it doesn't do anything to the server. This is a client command
line option for enabling the OpenGL accelerated rendering backend.

But now I get
this mysterious ImportError

When I run strings on that _gdkgl.so, I get the following
bash-4.4$ strings _gdkgl.so | grep gdk_window_is_gl_capable
gdk_window_is_gl_capable
_wrap_gdk_window_is_gl_capable
_wrap_gdk_window_is_gl_capable
and the function is defined in the following include file
/home/tools/include/gtkglext-1.0/gdk/gdkglwindow.h
bash-4.4$ grep gdk_window_is_gl_capable gdkglwindow.h
gboolean gdk_window_is_gl_capable (GdkWindow *window);

Looks like your build of pygtkgl is not quite right.
This is unrelated to the missing window problem.

During startup the xpra server probes the vfb's OpenGL capabilities by
running "xpra opengl" in a subprocess (so it won't crash the server if
opengl is somehow badly misconfigured to the point of causing crashes)
The message you are seeing just means that the probing fails.

Post by Ben Sferrazza via shifter-users
Perhaps the issue of not getting a window drawn is unrelated to the
ImportError, but I'd like to fix both of these issues. Thank you for any
help in solving this!

Is the window not being drawn, or not being shown at all?

Are you sure that the application (konsole in this case) is still
running and hasn't just crashed?
The best way to debug this is to launch an xterm instead, then run your
applications from there. Or maybe even with gdb if it does crash.

As for the gdkgl error, this is a build issue. I would just ignore it
and remove the package. Unless you also intend to use this same system
as an xpra client, in which case you do want accelerated rendering...

Cheers
Antoine

Thanks. Certainly wasn't easy at first, and had to make quite few tweaks
and workarounds along the way.

correct. I start xpra using '-d all'

xpra start :100 --start-child=xterm --socket-dirs=~/.xpra -d all

Post by Ben Sferrazza via shifter-users
So I then went ahead and installed gtkglext and the Python bindings,
thinking it was somehow related to OpenGL.

It was just a hunch. Perhaps a poor one. I believe to be using Xdummy. I
have the latest Xvfb as part of the xorg-server-1.19.6 tar ball. I placed
the following line in my /home/tools/etc/xpra/xpra.conf

xvfb=Xorg -dpi 96 -noreset -nolisten tcp \
+extension GLX +extension RANDR +extension RENDER \
-logfile ${HOME}/.xpra/Xvfb-10.log -config
/home/tools/etc/X11/xorg.conf

I have built and installed the latest xf-video-dummy, am using the
xorg.conf provided by Xpra. Is this sufficient to be using Xdummy?

I'll have to give VirtualGL a try. These servers at work are headless
multi-Xeon CPU systems without much of a video card. An lspci -v | grep VGA
returns

0a:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. G200eR2
(rev 01) (prog-if 00 [VGA controller])

The are completely modern systems, so I find it odd that it would have a
video card from the late 90s in it.

OK, the latter is reassuring. Using both the latest sources from the git
repositories of gtkglext and pygtkglext, I had to use the patch file you
created as part of https://www.xpra.org/trac/ticket/226 to get it to even
build correctly. The only change I made to the patch was removing the OSX
dependent paths in configure.in. $TOOLS = /home/tools.

konsole is just the KDE terminal program. But good point. Changing it to
xterm seems to suggest I'm not even connecting. I am prompted for my
password and the Xpra client (Windows) disappears. Seems to be running as
per taskmgr, but the tray icon goes away.

So it's as though it's not even aware of the attempt client connection?

It's probably unrelated but I receive this error immediately when starting
Xpra. This again is run as non-root. I have XDG_RUNTIME_DIR set to a path
in my home directory. So I'm not sure why it's still attempting to access

Figured I'd add the Xorg log file, with the Modeline lines stripped out.
Not sure why it's trying to load libinput when it's using the dummy_mouse
and dummy_keyboard.

sure to build all the Xpra dependencies and built it with
--prefix=/home/tools, which is where my updated environment is.

Impressive!
I am considering using a similar approach (maybe using snap / flatpack /
appimage) to continue to support CentOS 6 in the future.

Thanks. Certainly wasn't easy at first, and had to make quite few tweaks
and workarounds along the way.

correct. I start xpra using '-d all'

Post by Ben Sferrazza via shifter-users
So I then went ahead and installed gtkglext and the Python bindings,
thinking it was somehow related to OpenGL.

It was just a hunch. Perhaps a poor one. I believe to be using Xdummy. I
have the latest Xvfb as part of the xorg-server-1.19.6 tar ball. I placed
the following line in my /home/tools/etc/xpra/xpra.conf
xvfb=Xorg -dpi 96 -noreset -nolisten tcp \
+extension GLX +extension RANDR +extension RENDER \
-logfile ${HOME}/.xpra/Xvfb-10.log -config
/home/tools/etc/X11/xorg.conf
I have built and installed the latest xf-video-dummy, am using the
xorg.conf provided by Xpra. Is this sufficient to be using Xdummy?
I'll have to give VirtualGL a try. These servers at work are headless
multi-Xeon CPU systems without much of a video card. An lspci -v | grep VGA
returns
0a:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. G200eR2
(rev 01) (prog-if 00 [VGA controller])
The are completely modern systems, so I find it odd that it would have a
video card from the late 90s in it.

Post by Ben Sferrazza via shifter-users
However, passing --opengl=no on
the command line when starting xpra appeared to do nothing.

Correct, it doesn't do anything to the server. This is a client command
line option for enabling the OpenGL accelerated rendering backend.

Looks like your build of pygtkgl is not quite right.
This is unrelated to the missing window problem.

OK, the latter is reassuring. Using both the latest sources from the git
repositories of gtkglext and pygtkglext, I had to use the patch file you
created as part of https://www.xpra.org/trac/ticket/226 to get it to even
build correctly. The only change I made to the patch was removing the OSX
dependent paths in configure.in. $TOOLS = /home/tools.
+CFLAGS="$CFLAGS -I$TOOLS/include/gtkglext-1.0 -I$TOOLS/lib/gtkglext-1.0/include

konsole is just the KDE terminal program. But good point. Changing it to
xterm seems to suggest I'm not even connecting. I am prompted for my
password and the Xpra client (Windows) disappears. Seems to be running as
per taskmgr, but the tray icon goes away.

Figured I'd add the Xorg log file, with the Modeline lines stripped out.
Not sure why it's trying to load libinput when it's using the dummy_mouse
and dummy_keyboard.

sure to build all the Xpra dependencies and built it with
--prefix=/home/tools, which is where my updated environment is.

Impressive!
I am considering using a similar approach (maybe using snap / flatpack /
appimage) to continue to support CentOS 6 in the future.

Thanks. Certainly wasn't easy at first, and had to make quite few tweaks
and workarounds along the way.

correct. I start xpra using '-d all'

Post by Ben Sferrazza via shifter-users
So I then went ahead and installed gtkglext and the Python bindings,
thinking it was somehow related to OpenGL.

It was just a hunch. Perhaps a poor one. I believe to be using Xdummy. I
have the latest Xvfb as part of the xorg-server-1.19.6 tar ball. I placed
the following line in my /home/tools/etc/xpra/xpra.conf
xvfb=Xorg -dpi 96 -noreset -nolisten tcp \
+extension GLX +extension RANDR +extension RENDER \
-logfile ${HOME}/.xpra/Xvfb-10.log -config
/home/tools/etc/X11/xorg.conf
I have built and installed the latest xf-video-dummy, am using the
xorg.conf provided by Xpra. Is this sufficient to be using Xdummy?
I'll have to give VirtualGL a try. These servers at work are headless
multi-Xeon CPU systems without much of a video card. An lspci -v | grep VGA
returns
0a:00.0 VGA compatible controller: Matrox Electronics Systems Ltd.
G200eR2 (rev 01) (prog-if 00 [VGA controller])
The are completely modern systems, so I find it odd that it would have a
video card from the late 90s in it.

Post by Ben Sferrazza via shifter-users
However, passing --opengl=no on
the command line when starting xpra appeared to do nothing.

Correct, it doesn't do anything to the server. This is a client command
line option for enabling the OpenGL accelerated rendering backend.

Looks like your build of pygtkgl is not quite right.
This is unrelated to the missing window problem.

OK, the latter is reassuring. Using both the latest sources from the git
repositories of gtkglext and pygtkglext, I had to use the patch file you
created as part of https://www.xpra.org/trac/ticket/226 to get it to
even build correctly. The only change I made to the patch was removing the
OSX dependent paths in configure.in. $TOOLS = /home/tools.
+CFLAGS="$CFLAGS -I$TOOLS/include/gtkglext-1.0
-I$TOOLS/lib/gtkglext-1.0/include -I$TOOLS/include/"

Post by Ben Sferrazza via shifter-users
Perhaps the issue of not getting a window drawn is unrelated to the
ImportError, but I'd like to fix both of these issues. Thank you for

Well this actually made me realize I never install the fonts to
/home/tools/share/X11/fonts/, so I did that and re-built Xorg server. So
now I can actually see the connection established by Xpra. Making some
progress.

It is likely that the connection has been closed by the other end.
So you won't find the answer here, try the client debug output.

Using the current xorg.conf should work with an Xorg server with the

[3017181.013] (WW) DUMMY(0): Option "ConstantDPI" is not used

You may want to apply our "constant DPI" patch for better DPI support
with applications that calculate a "hardware DPI".

OK thanks for the suggestion. I see quite a few patches there as part of
ticket 163. Any particular ones I should apply given the system I described
in my first email?

Using the current xorg.conf should work with an Xorg server with the
dummy driver only, I don't think we require any other modules.

Are you sure that you are using the current xorg.conf from xpra?
We have stopped using the "void" module a long time ago.

I was using the one linked to on the Xdummy wiki page. I now just replaced
it with (...)/etc/xpra/xorg.conf. No more void module errors, but I do see

Assuming that you've built the latest 0.3.8 version of the dummy driver,
then the only patch you need on top of that is the "constant dpi" patch:

OK thanks. Xpra server is running as shown here. Its own log file doesn't
seem to react to the client connecting from below.

That's because it never gets a connection from the client, see below.
So, it seems that you're using SSH. I always advise to try with plain
TCP or SSL first before introducing a transport intermediary like SSH.

OK. I thought as a regular user I wouldn't have access to bind to TCP
ports. I at least know I can SSH into these machines.

seems to be the most glaring.

If you started the server using the same user account, it should have
placed a "run-xpra" script in one of the locations that the client will

/usr/local/bin/xpra
Note that XDG_RUNTIME_DIR may not be set when logging in via ssh if you
had to hack it previously. But ~/.xpra/run-xpra should exist anyway.
I'm just mentioning for completeness.

OK, yes those files do indeed exist.

And here is your problem.
Something in your user environment is printing out some text to the SSH
terminal connection which xpra uses to communicate with the xpra server.
When it sees that this isn't xpra's protocol, it drops the connection.
Either clean this up from your user's login scripts or use TCP / SSL
connections instead.

I commented out the line that sources a tool setup script (for Cadence CAD
software that echos back stuff) in my shell rc file. I can now launch an
xterm window!! Thank you. I suppose I can always source that too setup
script on demand when I actually need it, as opposed to sourcing it always
in my shell's rc file.

OK thanks. Xpra server is running as shown here. Its own log file doesn't
seem to react to the client connecting from below.

OK. I thought as a regular user I wouldn't have access to bind to TCP
ports. I at least know I can SSH into these machines.

Only ports lower than 1024 require special privileges.
See CAP_NET_BIND_SERVICE on Linux.

then

/usr/local/bin/xpra _proxy :100;else echo "no run-xpra command found";

exit

Or you can source it and redirect its output to a file or /dev/null

Cheers

Hi. I'm including my previous correspondence below, as it will at least
offer some history about my setup and prior issues.

I stopped using Xpra a few months ago due to numerous bugs that made it
unusable (this is using a Linux server and Windows client).

1. windows get stuck with on-top focus
2. disappearing mouse cursor when using X11-only no-toolkit apps that use
inverted black mouse pointer after clicking on something
3. some windows don't show window bar until resized (e.g. gvim always gets
placed in upper-left without window bar)
4. dialog box black bars (appears to be trying to add scrollbars?).
5. windows are all blank (white) when returning into work after several
hours (requires restarting client)
6. flickering clipboard icon in systray

I'm inclined to give Xpra another chance, with the newer versions, and can
hopefully provide actual debugging log information for these bugs to be
fixed (if they haven't already).

But I'm now not even able to connect to the server from the client using
version 2.3.3. It reports Connection Lost immediately. I can ssh into the
same host without issue. And have made sure that the shell rc file no
longer outputs anything, which was the source of my issue a few months ago.
I have included the relevant sections of the server log and client log
below.

Hi. I'm including my previous correspondence below, as it will at least
offer some history about my setup and prior issues.
I stopped using Xpra a few months ago due to numerous bugs that made it
unusable (this is using a Linux server and Windows client).
1. windows get stuck with on-top focus

Which windows from which applications?

Post by Ben Sferrazza via shifter-users
2. disappearing mouse cursor when using X11-only no-toolkit apps that use
inverted black mouse pointer after clicking on something

Do you have a specific application we can use to reproduce the problem?

Post by Ben Sferrazza via shifter-users
3. some windows don't show window bar until resized (e.g. gvim always gets
placed in upper-left without window bar)

Post by Ben Sferrazza via shifter-users
4. dialog box black bars (appears to be trying to add scrollbars?).

Can you provide example applications we can use to reproduce the problem?
I've never seen that anywhere except when X11 windows are smaller than
the minimal window size on mswindows, then we have to pad it with something.

Post by Ben Sferrazza via shifter-users
5. windows are all blank (white) when returning into work after several
hours (requires restarting client)

That's a known "feature" of some opengl drivers, they clear the video
memory when the system goes into idle or suspended state.
We try to detect that (slowing down the refresh rate) and then refresh
the screen when the session resumes, but that doesn't always fix things.
You should not need to restart the client: minimizing the windows and
restoring them should be enough.
Alternatively, turn off opengl in the client - the client performance
will be much lower.

6. flickering clipboard icon in systray

Post by Ben Sferrazza via shifter-users
I'm inclined to give Xpra another chance, with the newer versions, and can
hopefully provide actual debugging log information for these bugs to be
fixed (if they haven't already).

Bugs that are reproducible are usually fixed pretty quickly.
Unfortunately, I have not seen any of the problems you have reported
above, so the chances that newer versions have already fixed those
issues are slim.
For more generic bug reporting and debugging guidelines, see:
https://xpra.org/trac/wiki/ReportingBugs

Post by Ben Sferrazza via shifter-users
But I'm now not even able to connect to the server from the client using
version 2.3.3. It reports Connection Lost immediately. I can ssh into the
same host without issue. And have made sure that the shell rc file no
longer outputs anything, which was the source of my issue a few months ago.
I have included the relevant sections of the server log and client log

While I was debugging the issue yesterday, I figured I'd update my Xorg X
server to the latest version, 1.20.1. This seems to have broken things when
loading the Xdummy module, as the ABI versions no longer match.

Is the dummy_drv part of Xpra? Is there a possibility for this to be
updated? For now I just rolled back to X server 1.19.6 and everything works.

[904276.126] (II) LoadModule: "glx"
[904276.130] (II) Loading /home/tools/lib/xorg/modules/extensions/libglx.so
[904276.155] (II) Module glx: vendor="X.Org Foundation"
[904276.155] compiled for 1.19.6, module version = 1.0.0
[904276.155] ABI class: X.Org Server Extension, version 10.0
[904276.155] (II) LoadModule: "dummy"
[904276.162] (II) Loading /home/tools/lib/xorg/modules/drivers/dummy_drv.so
[904276.162] (II) Module dummy: vendor="X.Org Foundation"
[904276.162] compiled for 1.19.6, module version = 0.3.8
[904276.162] Module class: X.Org Video Driver
[904276.162] ABI class: X.Org Video Driver, version 23.0
[904276.162] (WW) dummy: module ABI major version (23) doesn't match the
server's version (24)

*So, I installed the latest MS Windows beta and explicitly used paramiko as
the ssh client. This solved my issue and can now connect to my Xpra server
running on Linux*. This was not an issue in Xpra 2.2, so I imagine
something in 2.3 changed the way it interfaces with the shell?

Thanks,
Ben

Sorry for the basic question, but is this still just a client option? It's
not something I would pass as an argument when building on the server side,
correct?

I do not intend to use this system as a client. Thank you for your help!

Ah. In that case, you may prefer building trunk which supports a native
opengl backend that does not need pygtkgl.
Use it with: --opengl=native

Sorry for the basic question, but is this still just a client option? It's

Yes, as per the man page, the "opengl" option is an "option for attach".
There is no such option when building.

Now that I've established a connection again with Xpra server 2.3.3, I
can try to address some of the issues I was/am experiencing. I haven't
used it enough to encounter the first two issues, which were the most
debilitating and largely made it unusable for me before (the stuck focus
issue and the disappearing mouse cursor). Once I can re-create those
I'll have more to offer.

Post by Ben Sferrazza via shifter-users
Hi. I'm including my previous correspondence below, as it will at

least

Post by Ben Sferrazza via shifter-users
offer some history about my setup and prior issues.
I stopped using Xpra a few months ago due to numerous bugs that

made it

Post by Ben Sferrazza via shifter-users
unusable (this is using a Linux server and Windows client).
1. windows get stuck with on-top focus

Which windows from which applications?
This was by far the most egregious bug. It seemed to happen at random
and affected all applications. Considering I do a lot of work in a
terminal, chances are it was a terminal such as xfce4-terminal. I will
report back once this occurs again. My only solution was to minimize the
window, rather than simply clicking on another window to give it focus.

This does ring a bell, but I don't think I ever saw it myself.
https://xpra.org/trac/ticket/713
https://xpra.org/trac/ticket/1381

This could be a platform specific bug (ie: affecting mswindows clients)
in which case the newer Python3 GTK3 builds may fare better.

2. disappearing mouse cursor when using X11-only no-toolkit apps

that use

Post by Ben Sferrazza via shifter-users
inverted black mouse pointer after clicking on something

Do you have a specific application we can use to reproduce the problem?
Unfortunately the application I encountered this issue with the most was
Cadence's Simvision, a digital simulation waveform viewer that's part of
their CAD/EDA software suite. The only observation I had was that it is
an application which does not make use of a modern toolkit, such as GTK.
Perhaps it's using Motif? When you click on a menu the mouse cursor
inverts to a right-pointing black cursor, which is a cursor internal to
the program and is not replaced by the client's cursor. That's when the
menu items would disappear. I've attached a screenshot of it working,
which required using an actual camera, as the inverted black cursor is
not picked up by the Windows print screen function.

There were bugs in the cursor code on mswindows, including some fixed
quite recently, those could have caused the problems you describe - it
should now revert to the default cursor in case of failure.

3. some windows don't show window bar until resized (e.g. gvim

always gets

Post by Ben Sferrazza via shifter-users
placed in upper-left without window bar)

Some applications do weird things with their geometry sometimes, gvim is
one of those. That said, I've just tried it and it worked fine and it
does seem to request to be placed in the top left corner.
Please provide more details so we can reproduce the window bar problem.
(ie: server os and version, gvim version, etc..)
This isn't a showstopper. I'm using gvim 8.0.586 with the latest Xpra
2.3.3 on Linux l-server-13 2.6.18-398.el5 #1 SMP Tue Sep 16 20:50:52 EDT
2014 x86_64 GNU/Linux. I've attached a screenshot showing this behavior.
It corrects itself once I do any resizing of the window (which must
initiate a redraw event). Perhaps Xpra could force a redraw event after
opening the window?

I bet it's not a redraw event but a window "configure notification" that
gvim is waiting for. If I can reproduce this, it should be fixable. We
can synthesize an event if needed.
What's the server version? CentOS 7.5?

Post by Ben Sferrazza via shifter-users
4. dialog box black bars (appears to be trying to add scrollbars?).

Can you provide example applications we can use to reproduce the
problem?
I've never seen that anywhere except when X11 windows are smaller than
the minimal window size on mswindows, then we have to pad it with
something.
Perhaps that's all it is.

Sadly, it's not. From the screenshot you attached, this looks like a
different problem.

Post by Ben Sferrazza via shifter-users
Certainly not a big deal, and just a cosmetic
annoyance. I've attached an example of this issue from a dialog box that
pops up using diffuse. Perhaps this would be too much work, but a
slightly more pleasing visual than black bars would be to sample the
color of the edge pixels and use this color (or an average of samples)
to extend the window to the minimum size.

Fixing the problem might be easier. (it looks similar to the gvim
problem - the application gets the window geometry wrong)
Do you have a sample application I can use to reproduce it?

6. flickering clipboard icon in systray

That's a very obvious sign that something is not right and something is
constantly requesting the clipboard contents. This will cause
unnecessary traffic and instability. Try to figure out what is causing
this and stop it. Usually, this is caused by clipboard managers or other
clipboard synchronization tools (synergy, virtualbox, etc).
Hmm. I don't have anything running like that. No VNC session,
VirtualBox, etc. Microsoft's Remote Desktop is enabled, but certainly
nothing is currently connected to it. It seems to flicker at a rate of
once every 4 seconds or so.

OK, then it's not so bad that it will cause instability.
Some clipboard managers request the clipboard contents as soon as
they're available, swamping the system with clipboard events.
If you wish, you can confirm the rate of change by running the client
with: "--debug=clipboard"

Post by Ben Sferrazza via shifter-users
It seems periodic, in the mathematical sense
of the word. My PC at work is a standard issue Dell box. It has the
typical Dell bloatware and some Symantec security software (not much
control over this), but can't think of anything that could be
potentially interfering with the clipboard. Any suggestions how to
determine the cause?

Sorry, I don't know how. The API we use to interact with the clipboard
does not offer any information about the application which set or
queried the clipboard. Some third party tools may exist to monitor the
system at this level.

Cheers,
Antoine

Actually the primary machine I use it on is CentOS 5.11 (unfortunately
needed apparently to support an older version of Cadence IC5). Though I did
build an entirely bootstrapped toolchain on this machine, so its using the
latest glibc (2.19) for the older kernel it uses (2.6.18), as well as the
latest versions binutils and gcc. Xpra and all of its dependencies were
built against this toolchain. However, I did just run Xpra 2.3.3 on a
CentOS 7 machine we have here at work and with that same version of Gvim
(8.0.586) I experience the same issue of it going to the top left corner
and not showing the title bar until the window is resized.

It was happening using diffuse (the graphical diff tool). If I'm comparing
two files and edit one of them outside of diffuse, diffuse will pop up a
dialog asking if you'd like to reload the file since it detected a change.
That small dialog was showing the black borders. However, I'm not seeing
the same issue again. Though there is another issue that could perhaps be
masking this. For some reason, many of my GTK applications (diffuse, gvim,
etc) are not using the window decorations and icons I have chosen when
using Xpra. This was working just fine in Xpra 2.2, and the correct theme
and icons are shown when I VNC into the same machine. Oddly enough, Emacs
does use the correct decorations even with the latest Xpra.

You should not need to restart the client: minimizing the windows and

Alternatively, turn off opengl in the client - the client performance

Tried the Python3 builds of the Xpra 2.4 Windows client and unfortunately
it has a lot of graphics artifacts (ghosting when moving a terminal, some

terminal, some applications being completely washed out and illegible,
etc). I'll continue to use the standard 2.4 build for the time being.

Oh! The GTK3 port is meant to be almost complete... (at least for the
client, the server will need a lot more work)
This could be because of transparency issues. (I have no idea why a
terminal applications would use an alpha channel but some do..)
Was this with xfce_terminal again?
Did you have OpenGL enabled or disabled? (see systray menu toggle)
OK. I'm still on 2.3.3 for the server. I had tried the latest 2.4 Python
3 beta for Windows but had those issues. You're right that the terminal
background transparency was the cause for its ghosting (not sure if
there's a way to actually have the transparency work, as that would be
pretty cool). But still had washed out colors with the Cadence
applications I've mentioned (picture attached). OpenGL was disabled
(showing as n/a on the client) and have attached a picture of the
session information. Perhaps I should try getting OpenGL enabled?

Transparency normally works just fine, bar some platform quirks:
https://www.xpra.org/trac/ticket/1570
ie: we just don't use OpenGL on mswindows for windows with transparency
because it cannot be done with GTK3:
https://www.xpra.org/trac/ticket/1682

The visual artifacts you are seeing could be something caused by the
outdated libraries or bugs in CentOS 5.11, this is an unusual /
unsupported setup you have after all.

Anyway, you can turn off transparency completely on the server or on the
client with:
XPRA_ALPHA=0 xpra start ...
or
XPRA_ALPHA=0 xpra attach ..
