Bug 480979

Application: plasmashell (5.27.10)

Qt Version: 5.15.12
Frameworks Version: 5.114.0
Operating System: Linux 6.7.2-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
Just updated Mesa and now both Wayland and X11 sessions either use the software renderer on login, or display a black screen with functioning cursor. Upon setting the renderer to OpenGL and logging out and back in with X11, Plasma crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
