Screenshot showing the artifacts
Playing a game on wine (NekoPara on steam), and got texture artifacts. I don't
really know what causes it since I can't reproduce it on my own, but I created
an apitrace to help with testing.
Some things I found out, artifacts disappear when:
1) LIBGL_ALWAYS_SOFTWARE=1 is set, or
2) glTexStorage2D is forced use no mipmaps, or
3) glTexImage2D is used instead of glTexStorage2D
Tested on OpenSuse Tumbleweed 64bit with latest mesa (11.2 and git 12.0), with
amdgpu and a Radeon R9 285.
Issue is not present when tested on another system, apitrace works on another
PC.
Screenshot attached.
