With latest Mesa master, The Witcher 3 in Wine started perform=
ing worse and it
also introduced noticeable flickering (once in a few seconds).

I was able to narrow down this flickering to these commits by Marek:

adab7f16ffd3ea4c52e8d07f40ca6ae4868c3706 2017-11-06 radeonsi: don't map big
VRAM buffers for the first upload directly

4b0dc098b2561c07c59f7dab2813640a25789bf1 2017-11-06 gallium/u_threaded: don=

up tc_improve_map_buffer_flags and prevent reentry

One commit before them this flickering doesn't occur:

OpenGL renderer string: AMD Radeon (TM) RX 480 Graphics (POLARIS10 / DRM 3.=
18.0
/ 4.13.0-1-amd64, LLVM 5.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.4.0-devel
(git-60a9705e00)

And with them, it does:

OpenGL renderer string: AMD Radeon (TM) RX 480 Graphics (POLARIS10 / DRM 3.=
18.0
/ 4.13.0-1-amd64, LLVM 5.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.4.0-devel
(git-adab7f16ff)

I'm running The Witcher3 with mesa_glthread and csmt enabled (both). You can
use latest Wine staging to test it.
