Description Noah Engle 2023-05-08 20:31:19 UTC

Application: kamoso (22.12.3)

Qt Version: 5.15.9
Frameworks Version: 5.105.0
Operating System: Linux 6.2.14-300.fc38.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 38 (KDE Plasma)
DrKonqi: 5.27.4 [KCrashBackend]

-- Information about the crash:
When I tried to launch Kamoso from the gui, I would get the little bouncing icon for a few seconds and then nothing. I waited a minute longer because I know that my laptop is quite slow, but still nothing. Attempting to start Kamoso from the terminal still made me wait a bit, but then a window appeared that would desaturate and say "(Not Responding" whenever focused. After a while, it crashed. I don't know if Dr Konqi includes terminal output, so I'll add it myself

New crash information added by DrKonqi

kamoso (23.04.2) using Qt 5.15.10

On the same install it works with default kernel which does not support device's cameras. Started crashing with linux-surface kernel (6.3.9-1.surface.fc38.x86_64) which, in theory, should support them.
