I'm getting a peculiar rendering bug in the game GTA IV (using Wine). The bug
could best be described as "christmas lights" (screenshot attached).

Apitrace (439 MB)

The bug happens both with 11.1.2 and recent git 1883613

The trace renders fine with i965 and with software rendering but with a lot of
warnings. 

Replaying the trace with radeonsi gives this warning:
16375: message: shader compiler issue 1: Shader Stats: SGPRS: 80 VGPRS: 12 Code
Size: 72 LDS: 0 Scratch: 0 Max Waves: 10
