See attached image. While I was retesting many games in wine, I noticed that multiple games, when run in wine, show black background with dot grids instead of alpha blending, apparently. Reverting to 17.1.x fixed this. I haven't the patience or continuous power to my machine to git-bisect; the only thing I can help with is that it doesn't do this with LIBGL_ALWAYS_SOFTWARE=1, so it's likely a radeonsi bug rather than mesa core.
Hardware: Device: AMD Radeon R7 Graphics (AMD CARRIZO / DRM 3.18.0 / 4.13.2-gentoo, LLVM 5.0.0) (0x9874) OpenGL renderer string: AMD Radeon R7 Graphics (AMD CARRIZO / DRM 3.18.0 / 4.13.2-gentoo, LLVM 5.0.0)
Note that this has been broken since the earliest rc I tried, also with earlier releases of the kernel and llvm, firmware from both before and after 06 Sept.
Apologies if this has already been reported; I can't really tell and it has been broken now for at least all rcs I've tried, 17.2 release, and 17.2.1.
