Description Luca Saalfeld 2024-03-24 14:11:09 UTC
SUMMARY
I have gotten 3 kwin segfault (so far) while playing games. They're quite random. Sometimes it's after hours, sometimes near instantly.

The latest journalctl logs:
> kwin_wayland[1363]: segfault at 7fff89576f88 ip 00007a5f2bd681c7 sp 00007fff89576f90 error 6 in libkwin.so.6.0.2[7a5f2bd45000+455000] likely on CPU 9 (core 1, socket 0)

Coredumps are available, although I have not interacted with one *at all*.

STEPS TO REPRODUCE
1. Play a game
Note: The segfaults are not consistent at all. As of writing this, there is no way to consistently crash Kwin.

OBSERVED RESULT
Kwin segfaults

EXPECTED RESULT
Kwin doesn't segfault

This unfortunately does not contain enough information to be actionable. Hopefully other coredumps from other users will fix this issue.
