Avidemux freezes screen on KDE with Nvidia drivers

[teaadmirer]

Screen freeze comes in a couple seconds if a window with a video is open, otherwise the window just hangs there and I can't even kill it. This is the error it keeps producing.

--platform xcb flag, but I believe an nvidia update ruined it. Wayland version does not work for me.

Just to be sure: Avidemux doesn't work on Wayland. Don't even try. In Qt6 builds, OpenGL is broken on Linux with Qt > 6.3.

Idk, a friend of mine launched it on wayland and said it worked normally. No flags used. They've got a different GPU though.

If Avidemux works for someone on Wayland (it doesn't for me), it would be valuable to know the details (desktop environment, software versions etc., video output used). If all we can use is the unaccelerated "Qt" output where the CPU does all the scaling and color conversion with video decoded in software only, that is not fun.

In general, Wayland is currently entirely unsupported, quality patches desperately welcome.

sway 1.8.1 , qt 5.15.11, avidemux 2.8.1 libva 2.20, but they have xwayland so maybe it is just xwayland

Ok. It works now. I don't know if updates fixed it or what, but I had another program not working and installing lib32-nvidia-utils made it work (it was a 32-bit).
