USB-C DisplayPort on GPU module is broken on Linux

I have tried both Nobara and Bazzite so far, and these are both based on Fedora. Bazzite is a community-supported OS.

When using the USB-C connection on the back of the GPU to connect to an external monitor, running certain games (Timberborn is extremely consistent) on Steam with KDE Wayland causes a full system crash. I cannot ctrl+alt+f3 to change the tty to kill the broken programs.

I have submitted a bug report on KDE’s side in case it’s something to do with them, but I have a feeling it’s more likely an issue with the GPU drivers or possibly even the hardware.

Here is an example of what happens right before the crash too: Imgur: The magic of the Internet

Has anyone else run across this issue? It would be lovely to know I’m not alone, and if I am alone, maybe it really is a hardware issue somehow?

I can’t find anyplace to even submit a bug to AMD/mesa, does anyone know where I can do that?

Both are on the freedesktop.org gitlab.
