Rocket League ingame artifacts
radeonsi on mesa 19.2.0 / GFX8. This is unrelated to #1888 (closed).
While ingame, some artifacts randomly appear, most frequently when a countdown is displayed on the OSD at the start of a game. It's very brief so I haven't been able to take a screenshot of it.
AMD_DEBUG=nodma
seems to fix the issue. I played two games in a row without any artifacts, while I usually get several of them during a single game without the flag.
SDMA image copies were already disabled by 6b3ee869, it seems that SDMA buffer copies are also problematic and should be disabled.
