Description raffarti 2016-09-14 16:05:40 UTC 
Commit 524fd55d2d973f50a5d8bc2255684610f5faae32 "tgsi/scan: don't set interp flags for inputs only used by INTERP instructions" caused regression in gallium nine.

Observed glitches in:
    -terrain on WoW 32 bit wine, only with multisampling;
    -grass on LoL 32 bit wine;
    -terrain on LoL 32 bit wine, only with shadows.

The glitch looks like noise/corruption on texture surfaces.
