Bug ID: 439660
Summary: System Settings crashes when changing the Rendering
backend to XRender
Product: systemsettings
Version: 5.22.3
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: mlara...@pm.me
Target Milestone: ---
Application: systemsettings5 (5.22.3)
Qt Version: 5.15.3
Frameworks Version: 5.83.0
Operating System: Linux 5.8.0-59-generic x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.3
Distribution: KDE neon User Edition 5.22
-- Information about the crash:
- What I was doing when the application crashed:
I had a few processes with high cpu usage. I changed the Rendering backend to
XRender in the Compositor settings and System Settings crashed. This happened
twice, but does not happen every time I change the setting.
- Unusual behavior I noticed:
The whole desktop was unusually sluggish and unresponsive.
The crash can be reproduced sometimes.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
