Description Vlad Golovkin 2018-02-07 09:46:47 UTC
GPU info:
OpenGL renderer string: AMD RV710 (DRM 2.50.0 / 4.13.0-32-generic, LLVM 5.0.0)
OpenGL core profile version string: 3.3 (Core Profile) Mesa 18.1.0-devel (git-2d5b5d267e)

git bisect brought me to this commit:
Comment 1 Gert Wollny 2018-02-07 11:48:14 UTC
I can't confirm this neither for AMD BARTS, nor for AMD CEDAR on 
DRM 2.50.0 / 4.14.16-gentoo, LLVM 5.0.1 (0x68f9)

OpenGL core profile version string: 3.3 (Core Profile) Mesa 18.1.0-devel 

So I guess this bug only affects pre Evergreen cards.
Comment 2 Dave Airlie 2018-02-07 22:27:51 UTC

Should fix it, I tested on my rv770, sorry for breakage.
Comment 3 Vlad Golovkin 2018-02-08 22:07:10 UTC
I can confirm that this patch fixed rendering for me. Thank you.
