Lara's broken hair...

This weeks LLVM update somehow broke the rendering of TressFX in Tomb Raider.
Radeon HD 7970, Mesa Git

I use precompiled packages from arch repo.

For me last working: lib32-llvm-libs-svn-5.0.0svn_r296294
First time error appeared in: lib32-llvm-libs-svn-5.0.0svn_r296961

No other packages in between, sorry.

Can you either bisect LLVM, or create an apitrace which reproduces the problem?
Comment 2 Marek Olšák 2017-03-07 22:19:10 UTC 
Not sure but this might help: https://reviews.llvm.org/D30717
Comment 3 Gregor Münch 2017-03-19 15:54:23 UTC 
Fixed with current git / llvm.
Avg FPS seems to made a little jump too from 58 to 60fps.
