Created attachment 124320 [details] 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. Apitrace: http://www.mediafire.com/download/tk5z5r9ag0898qf/wine-preloader_NekoPara0.7z (35MB, 197MB unpacked)
Renders fine on nvc0 and nv50, both 11.2 and master. Sounds like a radeonsi issue, not mesa core.
apitrace is has corruption without parameters and is correct with R600_DEBUG=nodcc on a R9 285 here, so definitely seems like a radeonsi issue.
This seems to fixed. The output here looks the same on Tonga, Bonaire, and llvmpipe.
Can confirm that the issue isn't present anymore with a recent version of mesa.
