Comment # 35 on bug 93144 from Luzipher

Today, since compute shaders are committed to the mesa repo (commit    
7143068296aaca8c5af3469c013a7c2a850aee84) and the llvm repo this game runs
flawlessly with nothing but "MESA_GL_VERSION_OVERRIDE=4.3
MESA_GLSL_VERSION_OVERRIDE=430" (which isn't enabled yet due to some bug that
doesn't affect Alien Isolation). I didn't see any flickery colours on fog or
anywhere else during the first level (on the Torrens).

Setting this bug to resolved. Thanks for getting it working, devs ! :-)
