Hello @brandonegbert, can you check if setting the game's launch options to RADV_PERFTEST=aco %command% has an effect on the rendering and stability issues?
No, it's not set. Just retested with RADV_PERFTEST=llvm to be sure and still had it behave the same, though the artifact looked different (could be coincidence).

With mesa 20.1.1, LLVM is RADV's default shader compiler and RADV_PERFTEST=llvm doesn't do anything (the same as having nothing set). I was asking if the ACO shader compiler has different behavior from the LLVM default, not if you were using it in your initial test.
Ah, sorry about that. Same result with ACO.
Seems to work great now with 5.13-1.
