Note: Article has been updated to make it clear this is with later LLVM versions.
DiRT Rally [Steam, Feral Store] seemed to have an issue with rendering properly in certain cases with newer versions of LLVM with RadeonSI Mesa (AMD), but it seems to have been tracked down as an issue in LLVM.
https://t.co/P1nITBK8oG Samuel tracked down the last rendering issue with DiRT Rally on RadeonSI; renders properly with these patches.

I did notice an issue during Feral's livestream before release, which other people also noticed where the car dashboard wasn't rendering. Hopefully this is the fix for that, as I haven't heard about any other issues.
Looks like Feral helped directly, as the Linux Dev Lead from Feral also tweeted about helping to get it found.
I've been told this was actually a regression with LLVM 4.0, so it's good to see it get cleaned up. It's not a bug in the port itself, if that wasn't clear. So hopefully with later Mesa releases DiRT will continue to work nicely on Mesa.

Another one is the Tress FX hair in Tomb Raider, when you activate it and restart the game, Lara's hair is missing. Witch is shame, because it was working very well right before the bug, with little performance degradation.
Thanks - these are regressions then? I'm pretty sure Deus was rendering correctly a couple of months back (RX480) and I know Max was...
Just tried TressFX: So it does! Also Motion Blur causes issues (white ghosting). Mind you at max settings (no AA, no blur) I'm seeing an AVG 60FPS on the bench @3440x1440! Those Mesa devs have done good things :) <3
Yes, the progress in Mesa has been incredible. I remember a year ago when I had to use graphics at medium to low settings in Tomb Raider, Grid Autosport or Shadows of Mordor, and now those can be played at maximum settings.
If things continue at this pace, in one semester you have no motive to buy a Nvidia card for Linux use anymore.
Be this issue here then: [Bug 100095 - [Regression] Volumetric lighting result in white surface](https://bugs.freedesktop.org/show_bug.cgi?id=100095)
Interestingly, Marek believes it *might* be related...
