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) https://www.dropbox.com/s/7xto4gmvwkk5ksm/gtaiv.trace?dl=0

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
