Bug ID: 521227
Summary: Crash right after login, but KWin actually does not
close the session
Classification: Plasma
Product: kwin
Version First 6.6.91
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: kwin_wayland (6.6.91)
ApplicationNotResponding [ANR]: false
Qt Version: 6.11.1
Frameworks Version: 6.26.0
Operating System: Linux 7.0.11-zen1-1-zen x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.6.91 [CoredumpBackend]
-- Information about the crash:
After logging in and waiting a while (in the meantime I can do stuff like
firing up VSCodium) KWin triggers one or more crashes, which I don't know if
they are identical as they are not visible on drkonqi-coredump-gui, but
contrary to what pkill kwin_wayland would do, KWin still lives and the crash
does not cause a blackscreen and seems harmless but anyway it is a bit annoying
to see this every login.
The crash can be reproduced sometimes.
