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 pho= ne, the grey squares on a tree branch are the artifacts in question but they co= uld 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=3Dzerovram steam

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=3Dverbose LIBGL_DRIVERS_PATH=3Dpath_to_mesa_bin/lib/dri/
LD_LIBRARY_PATH=3D$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=3Dnohyperz? I have this kind of glitche= s 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=3D110635
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).
It helps, unfortunately it also reduces fps by around 15 - 20= %
It seems R600_DEBUG=3Dnodma 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.
