dmesg from boo
This is a semi recent (within the last few months) bug on Polaris in NSMBU.
Many polygons (maybe?) have major glitches across the screen, or don't show=
up
at all. This doesn't occur on Tahiti or Pitcairn. I've gone back to 18.2.1 =
and
verified it still exists, so it must be prior. It also exists on both linux
4.18.12 and the amdgpu-staging-drm-next branch. I'll continue attempting to
bisect, unless someone else knows exactly what the issue is.
There are quite a few GPU faults listed in the attached dmesg, though I'm n=
ot
sure if they're related to the issue. Glxinfo, Xorg.0.log, as well as a
screenshot of the issue.

Seems more likely to be an LLVM or Mesa bug than a kernel one.=

(In reply to Alex Deucher from comment #6) > Seems more likely to be an LLVM or Mesa bug than= a kernel one. I went back to 4.18.7 and it persisted, so you're correct. It was okay earl= y on at 18.2.0 with llvm svn. I'll go back to 18.2.0 to test, and if it's broken then we know it's llvm.
I attempted to bisect in Mesa, and found that I wasn't able to= get rid of the glitch. The regression must be in LLVM.
R600_DEBUG=3Dnir works around this issue. If requested, I can = provide apidoc of this rendering issue.

Is this still an issue with the development version of LLVM 9.= 0 ? There have been many LLVM bug fixes since this issue was reported.
