Example screenshot, showing artifacts in game.

After updating Mesa from 17.2.6 to 17.3.0 (using packages from Solus
distribution) both ETS2 and ATS started glitching (artifacts around the
objects, see attached screenshot as example).

Software: Linux 4.14.5, Mesa 17.3.0, LLVM 5.0.0.
Videocard: MSI Radeon R9 280X (using amdgpu kernel module).

Just did some research - this issue still persists in 17.3.1 and it's only
visible if shadows enabled. If I set "Shadow quality" in the in-game settings
to "Disabled", artifacts disappear.

Cant confirm with Radeon HD 7970 on mesa git and llvm git from today.
ATS with shadows to high.
Maybe its LLVM?

Solus started shipping Linux 4.15.3 and Mesa 18.0 RC4, but unfortunately the
problem is still there. After comment #4 I wonder if LLVM 6.0 will make the
difference...

I think it's not the same bug. CS:GO works on my system as it should, while SCS
games still have broken shadows.

So you also checked that specific map?

Anyway, its either a bug which is already fixed in Mesa git or fixed in LLVM
6.0. In both cases devs will wait till users upgrade to mesa 18.
So the only thing you can do is check things with current mesa git / LLVM 6.0
and see if the problem persists.

Can confirm that with LLVM 6 and Mesa 18.0.2 artifacts are gone.
Marking this as resolved.
