This freedesktop.org bug is a Mesa bug. The bug title is "Radeonsi ...".

If the visual artifacting issue is solved in radeon.ko, the patch will probably
be in short time applied to amdgpu.ko, and vice versa.

Support for R9 390/390X (Grenada) in amdgpu.ko is basically equivalent to
radeon.ko (at least on my machine). Performance is very similar too.

amdgpu.ko and radeon.ko are loading the same firmware files for R9 390/390X
(/lib/firmware/radeon/{hawaii,HAWAII}*.bin).
