Can you post output of `qdbus org.kde.KWin /KWin supportInformation`?
Comment 2 Andreas Sturmlechner 2019-06-05 11:00:34 UTC
Sure, this is from the same session:

KWin Support Information:
The following information should be used when requesting support on e.g. https://forum.kde.org.
It provides information about the currently running instance, which options are used,
what OpenGL driver and which effects are running.
Please post the information provided underneath this introductory text to a paste bin service
like https://paste.kde.org instead of pasting into support threads.

Comment 3 Vlad Zahorodnii 2019-06-05 11:10:43 UTC
Hmm, did you force the EGL platform interface?
Comment 4 Andreas Sturmlechner 2019-06-05 11:17:40 UTC
I see that GLPlatformInterface=egl is set in .config/kwinrc which may or may not be an artifact from long ago.
Comment 5 Andreas Sturmlechner 2019-06-05 11:45:52 UTC
No KWin crash with:
- mesa-19.0.5 and EGL platform interface
- mesa-19.1.0_rc4 and GLX platform interface
Comment 6 Vlad Zahorodnii 2019-06-05 11:55:17 UTC
So, this bug is reproducible only with Mesa 19.1.0-rc4, is it correct?
Comment 7 Andreas Sturmlechner 2019-06-05 12:03:11 UTC
Exactly right (probably earlier 19.1 RCs as well).
Comment 8 Vlad Zahorodnii 2019-06-05 12:04:38 UTC
Can you file a bug report upstream?
Comment 9 Andreas Sturmlechner 2019-06-05 12:06:17 UTC
This looks similar: https://bugs.freedesktop.org/show_bug.cgi?id=110814
Comment 10 Vlad Zahorodnii 2019-06-05 12:09:48 UTC
Yeah, it does.
