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:
https://cgit.freedesktop.org/mesa/mesa/commit/?id=2d5b5d267e1b0997ebe9fe7bcc06f6b79af48e43

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 
     (git-c74719cf4a)

So I guess this bug only affects pre Evergreen cards.

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.
