Silent Hunter 3 under wine (2.21 staging / 3.0rc4 as well) renders flickering
corrupted textures that seem to be UI elements all over the place for some of
its rendered frames, also 3D scene gets trashed every now and then.

Game worked fine on my previous hardware (intel Haswell HD4600) and same mesa
version 17.3.1, replaying the trace recorded while using polaris hardware
renders correctly on intel HD4600 (it is noteworthy however, that replaying the
trace throws more fragment shader errors on intel, so it could be possible it
renders with no errors because of missing shaders?).
