Summary: Kwin crashes on login with Wayland
Classification: Plasma
Product: kwin
Version: 5.27.7
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org

Target Milestone: ---
SUMMARY
Kwin crashes on login with Wayland
STEPS TO REPRODUCE
Try to log in to Wayland
OBSERVED RESULT
The SDDM splash screen appears for a brief moment, then the screen turns to
back, it appears to attempt to load plasmashell briefly as several widgwwwwbut
then it turns back to black again and the mouse appears on screen with no
plasmashell, just a black background. The system can still be used and
shortcuts work fine. I managed to launch konsole through a ctrl+alt+t, copy the
dump and then open firefox through konsole and that's how I write this bug
report.
It even somehow even sends notifications, albeit after freezing the system for
several seconds.
EXPECTED RESULT
Desktop loads normally like on X11.
