Hi, I was running a live stream in OBS and did a system upgrade, but when I tried to open OBS again, I got the "failed to initialize video gpu not supported linux" message. I tried the solution that I found online, running the command LIBGL_ALWAYS_SOFTARE=1 obs on the terminal, but it didn't work. When I click on the obs icon it just doesn't open, and when I run the command obs and the LIBGL one, I get this message:

Any tips? I tried removing it and installing it again but no luck.

Set the environmental variable QT_AUTO_SCREEN_SCALE_FACTOR=0 and or turn off high DPI scaling in your display options.
