Hi

I've been having issues starting the game with high settings at 4k resolution
on Tonga, at lower settings I'm seeing graphical glitches
https://www.youtube.com/watch?v=ZyKjahCamLQ

If I start the game in low settings and turn up the settings the game freezes
up (I've also had the same issues with high settings on DiRT)

I'm running agd5f's drm-next-4.8-wip branch, I've also tried with kernel 4.5 &
4.6

The issue goes away if I'm running llvm-3.8 & Mesa 11.2.2 or running llvm-3.8
with Mesa-git, I can't compile Mesa 11.2.2 with llvm-git

This is a prime system Skylake/Tonga - I don't have any issues starting these
games on Skylake or see any graphical glitches (of course the game is very slow
with these settings)

I think these are the same issues that were spotted on Phoronix too

Once the apitrace is uploaded I'll post the link
