Bug ID: 512671
Summary: Kwin segfaults when switching windows on different
virtual desktops using alt-tab on Wayland
Classification: Plasma
Product: kwin
Version First 6.5.3
Reported In:
Platform: Manjaro
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: kwin_wayland (6.5.3)
ApplicationNotResponding [ANR]: false
Qt Version: 6.10.0
Frameworks Version: 6.20.0
Operating System: Linux 6.17.9-1-MANJARO x86_64
Windowing System: Wayland
Distribution: Manjaro Linux
DrKonqi: 6.5.3 [CoredumpBackend]
-- Information about the crash:
I am getting spurious segfaults from kwin_wayland. I have so far identified
only two common properties: it happens when switching windows located on
different virtual desktops using alt+tab (different applications each time,
haven't found a reproducible trigger) and that the segfault happens due to
reading invalid pointer in a destructor of "something" (usually a QObject, but
a different one each time).
Right now I can't recover more of the old stack traces since I have updated
recently (from Manjaro testing to unstable aka to Arch versions) to try if it
will fix things (it didn't) but I'll try to upload new ones as they happen
(usually once or twice a day, depending of my screentime). From memory, common
symbols in the stack traces were QTimer, Kwin Texture and KSvg.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_wayland), signal: Segmentation fault
