screenshot of the glitch

I noticed white glitches in some games (namely The Vanishing of Ethan Carter
run using wine and Dreamfall Chapters, which is native). The glitches seem
random at first, as they manifest as random white specks, but they repeatedly
happen at the same place. This is true for both games - if I play the game and
I see the glitch in some place, I can be sure the glitch will be there the next
time I play.

I'm running current mesa from git with LLVM from git on Arch Linux. The package
versions are:

clang-svn 285849-1 
lib32-libdrm-git 5936.6493860-1 
lib32-llvm-libs-svn 285855-1 
lib32-mesa-git 86198.1d75d68-1 
lib32-mesa-libgl-git 86198.1d75d68-1 
libdrm-git 5936.6493860-1 
llvm-libs-svn 285849-1 
llvm-svn 285849-1 
mesa-git 86198.1d75d68-1 
mesa-libgl-git 86198.1d75d68-1

I have apitrace trace for the Vanishing of Ethan Carter with the glitch, but
the trace has almost 700MB when compressed, so I would need some place to
upload it.
