Bug ID: 480326
Summary: kwin segfault when starting GZDoom with the OpenGL
renderer
Classification: Plasma
Product: kwin
Version: 5.27.9
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: kwil...@sc.edu
Target Milestone: ---
Application: kwin_x11 (5.27.9)
(Compiled from sources)
Qt Version: 5.15.12
Frameworks Version: 5.111.0
Operating System: Linux 6.5.10_p1-debian-sources x86_64
Windowing System: X11
Distribution: Funtoo Linux
DrKonqi: 5.27.9 [KCrashBackend]
-- Information about the crash:
Frequently when I start GZDoom (a classic Doom source port), `kwin` segfaults.
GZDoom is using the OpenGL renderer when this happens. The compositor turns
off while GZDoom is running. The segfault reliably occurs every time.
Initially the GZDoom window is very small, despite being set to 1080p
resolution. I used a KWin window rule to force it to fullscreen without
decorations.
Dristribution method Other is "Funtoo packages"; KDE is available for Funtoo
Linux in a similar way as on Gentoo.
The crash can be reproduced every time.
