-- Information about the crash:
- What I was doing when the application crashed:
I was using Plasma 5.22.4 on Wayland with KF 5.83.0, Qt 5.15.2, Mesa 21.1.5 in
Fedora 34. I launched System Settings. I selected Display and Monitor >
Compositor. I then set the latency preference to balance of latency and
smoothness. I cliked on apply. System Settings crashed with segmentation fault.
The crash can be reproduced every time.
-- Backtrace:
