GTK3 OpenGL win32 window is transparent

[totaam]

Like it's not getting painted at all.

Tried 2.5.3 and 3.0.x on a win7 system with a Quadro M4000.

The code was originally added in r16993 + r16964, see #1569#comment:5.

try to use Gtk.GLArea

[totaam]

2019-10-30 15:38:01: antoine commented

Turns out that we may be able to use GTK.GLArea with legacy contexts: GTK Bug 756142 - Bring back support for legacy OpenGL contexts using the undocumented env var GDK_GL=legacy. (patch hooks the widget)

As per gdkglcontext-win32.c: * OpenGL does not work with WS_EX_LAYERED enabled, so we need to disable WS_EX_LAYERED when we acquire a valid HGLRC*
I've tried doing the same thing in the window style fixup code (removing WS_EX_LAYERED), but that did not help.

[totaam]

This may help if we have to use gtk.glarea: #2467 move to opengl core profile

[totaam]

As per #2469, this also seems to affect some linux drivers.

[totaam]

Easy fix in r24350 + r24351 + r24353, with older versions use:

XPRA_OPENGL_DRAW_REFRESH=1 ./Xpra_cmd.exe attach ...

Backport in r24352.

The fix is incorrect, it ends up disabling opengl because this now triggers a rendering error:

Error presenting FBO

The rendering error is fixed in r24365, but the window remains transparent..

[totaam]

"Fix" for now is to disable opengl on win32: r24369 + r24371.

Backport in 24374.

See also #2243 and r23305, maybe #2457 is related somehow?

[totaam]

Indeed, #2457 and #2475 were related and r24405 fixes all 3 bugs.

So r24405 partially reverts r24369 and r24371: we just keep the opengl variable substitution in the config file.
v3.x revert in r24406.

XPRA_OPENGL_DRAW_REFRESH=1 seems to have caused a performance regression: #2481

I guess I'm reopening this ticket.

With Xpra-Python3_Setup_3.0.4-24778.exe (on windows 7) launched against Fedora 30 server with xpra v3.0.4-24778 (I don't see a r24903 or later server version, mentioned in #1797, or client version available with dnf update on stable or pulling from /dists directory) with my new-usual server launch command of:

 xpra start :13 --no-daemon --bind-tcp=0.0.0.0:1234 --bind-ws=0.0.0.0:1237 --bind-wss=0.0.0.0:1239 --ssl-cert=/etc/xpra/148-ssl.pem  --start-child=xterm --start-child=xterm --exit-with-children

When the python client connects with opengl enabled, I am unable to display a chromium-browser launched from an xterm... though I am able to display firefox.

Attached new log.txt with a long list of client-side logs with -d opengl... which started with initial launch of session and then all the time it took to launch the chromium-browser in one of the xterms (which didn't display).

Attached log2.txt which is shorter, client-side logs from simply re-connecting to the same session with that chromium-browser application already running (which doesn't display) and then disconnecting within a second or three.

And, just for comparison, included opengl-off-log.txt capturing the logs with opengl disabled - which unsurprisingly results in a very short bit of logs, but seemed like it ought to be included just for completeness?

Happening again with a chromium window, but not the xterm. (just like #2514 - maybe should have gone there?)

Key elements from the logs:

OpenGL enabled with Intel(R) HD Graphics 530

[/wiki/ClientRendering/OpenGL#IntelDriverIssues Intel driver], we meet again.

Desktop-scaling is triggered by the large desktop size:

desktop size is 5760x2160 with 1 screen:
  Default (1524x571 mm - DPI: 96x96)
    Lenovo Wide viewing angle & High density FlexView Display 1920x1080 1920x1080 at 3840x1080 (344x194 mm - DPI: 141x141) workarea: 1920x1040
    (Standard monitor types) DELL UP3214Q 3840x2160 (698x392 mm - DPI: 139x139) workarea: 3840x2160
 upscaled to 125%, virtual screen size: 4608x1728
  Default (1524x571 mm - DPI: 76x76)
    Lenovo Wide viewing angle & High density FlexView Display 1920x1080 1536x864 at 3072x864 (344x194 mm - DPI: 113x113) workarea: 1536x832
    (Standard monitor types) DELL UP3214Q 3072x1728 (698x392 mm - DPI: 111x111) workarea: 3072x1728

The xterm window which does show up:

Initializing GL context for window size (624, 395), backing size (499, 316), max texture size=16384

I am guessing that the chromium window must be this one:

Initializing GL context for window size (1313, 853), backing size (1050, 682), max texture size=16384

Lots of h264 screen updates quite early on, but nothing unexpected otherwise.

@afarr: Looks to me like 24727 isn't doing what it is supposed to. As per #2514#comment:8: GTK3 is just buggy on win32 with undecorated windows, we are not supposed to use opengl on win32 with GTK3 if the window is not decorated. (I believe your chromium window draws its own decorations and does not use the default window manager decorations) Yet, from the logs, opengl seems to be used to try to draw it. Weird.

The only other possibility is some bad interaction between desktop-scaling and 24441 / 24483, does the problem go away if you turn it off? (either using --desktop-scaling=no or using the system tray menu).

If not, please post the -d window log of just when chromium is launched.

Using the same versions, when I launch the client with --desktop-scaling=no the chromium-browser still fails to display when launched (with greylisted but on opengl).

Got this from the -d window in client-side logs when launching the chromium-browser.
