I don't know if what I'm seeing is a GPU hang or just e.g. Proton getting somehow stuck, all I see is a game freezing. I just Alt+tab back to Steam, force-stop it, and then all is fine again. This is how it should work regardless of why a game freezes. However, even if it was a GPU hang, if I am on a display server that actually handles GPU resets, I don't see why the rest of the desktop would not be able to recover. Individual apps are each to their own, but at the very least non-GPU apps and the DE itself should not have any problem (DE components can simply be restarted automatically). Thanks, pq
