Bug#943893: glamor0: GL error: GL_OUT_OF_MEMORY in glTexSubImage



Package: xserver-xorg-core
Version: 2:1.20.4-1
Severity: important

Dear Maintainer,

X session crashes randomly, losing unsaved information.

Xorg.0.log (attached below) shows that a segfault is aborting the server.

Error starts with

  glamor0: GL error: GL_OUT_OF_MEMORY in glTexSubImage

Browsing for that error I found

  [Bug 110500 - X-Server crashes - GL error: GL_OUT_OF_MEMORY in glTexSubImage ]
  https://bugs.freedesktop.org/show_bug.cgi?id=110500

with a similar backtrace.

Very similar backtraces (but for /usr/bin/Xwayland instead of
/usr/lib/xorg/modules/libglamoregl.so) are reported in 

  [Sometimes my Ubuntu Log me out and close all applications]
  https://gitlab.freedesktop.org/xorg/xserver/issues/833.

and

  [https://gitlab.freedesktop.org/xorg/xserver/issues/647]
  https://gitlab.freedesktop.org/xorg/xserver/issues/647

This last one seems already fixed upstream, and there is a suggestion that
Xwayland 1.20.5 contains the fix. Since I see libglamoregl.so in my
backtrace I am setting xserver-xorg-core as affected package. Please
reassign if aprppriate.

Thanks for your work in xorg.

Regards,
