example of artifacts
Artifacts captured with OBS
Description Danylo 2019-05-01 20:38:55 UTC
Created attachment 144123 [details] example of artifacts Distro: Manjaro Kernel: 5.0.5 GPU: R9 380X Reproducible with: Mesa: git (07745f94948) LLVM: 9 (359393) Isn't reproducible with: Mesa: 19.0.3 LLVM: 8 Parts of the screen randomly become corrupted for 1 or 2 frames. It's not a rare event. Doesn't happen when capturing and/or replaying with apitrace. Doesn't happen when running OBS. Happens on new Sirocco map, didn't test on other. Sorry for the image quality - it was taken from video recorded with old phone, the grey squares on a tree branch are the artifacts in question but they could be completely different. I'm using https://pkgbuild.com/~lcarlier/mesa-git/x86_64/ for mesa and llvm builds.

Bit of a stab in the dark but if its related to bug #100239 You could try running steam from the command line with: R600_DEBUG=zerovram steam

Created attachment 144152 [details] Artifacts captured with OBS No luck with it unfortunately. Also I got one small artifact when captured the game with OBS but it happened only ones. I'm somehow unable to launch CSGO with non system mesa: LIBGL_DEBUG=verbose LIBGL_DRIVERS_PATH=path_to_mesa_bin/lib/dri/ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:path_to_mesa_bin/lib/ %command% &> ~/csgo.log CSGO launches and screen remains black forever without any errors in log. However other games work fine e.g. Rocket League. I don't know what I'm missing.

Can you try R600_DEBUG=nohyperz? I have this kind of glitches in almost every game with OpenGL/Gallium Nine on Polaris and this variable seems to help at least in Skyrim with Gallium Nine (haven't tested anything else so far). My bug report: https://bugs.freedesktop.org/show_bug.cgi?id=110635
Comment 4 Danylo 2019-05-22 15:14:25 UTC
I'll try it later when will come home, thanks. It also happens in Minecraft but much rarer (so I wasn't patient enough to bisect with it).
Comment 5 Danylo 2019-05-22 19:27:59 UTC
It helps, unfortunately it also reduces fps by around 15 - 20%
Comment 6 tempel.julian 2019-05-26 21:14:35 UTC
It seems R600_DEBUG=nodma helps as well and hardly costs any performance in CS:GO or Skyrim Gallium Nine.

I plan to disable SDMA image copies by default on dGPUs.
