Looks like there are more hangs to iron out in the ef2f620cbce5630c compute shader (initial report here: https://github.com/ValveSoftware/Proton/issues/8760#issuecomment-4930934737). To repro in retail WoW I've been idling on boats out of Stormwind where it hangs on loading into a new zone. I couldn't get it to hang with RADV_DEBUG=hang, but it does hang with syncshaders.

I also had a random page fault in WoW Classic with the same settings, but I haven't confirmed it's the exact same hang there yet.

Edit: The original reporter didn't have RT enabled, but so far I've only had glitches related to CMAA without RT and no hangs yet.
Edit 2: I did find a way to get GPU hangs with CMAA and no RT. If I switch monitor repeatedly, I get a page fault in a vertex shader. This doesn't happen with CMAA 2. This hang does happen with RADV_DEBUG=hang.
