I experienced some bugs while gaming on Wayland even with an amd card. My workaround was switching back to X11 for gaming. That said, I didn’t even notice that I was using Wayland by default for a long time until Firefox completely switched to Wayland I experienced some heavy artifacts in Firefox (only if it’s full screen on my second monitor, but that’s a daily thing). And because of that, switching back to X11 isn’t a workaround anymore, unfortunately its my new default.
Does your CPU has integrated graphics? You can remove your GPU and then you test if the error still occurs to find out if your GPU has damage. You can also test a live system, to exclude issues in your OS or driver configuration
Which OS and GPU do you have in use?
