Created attachment 136213 [details] 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.
I can confirm this bug. Radeon HD 7950 (amdgpu kernel module) kernel 4.14.0-4.14.11 mesa 17.3.0-17.3.0 LLVM 5.0.0-5.0.1
Cant confirm with Radeon HD 7970 on mesa git and llvm git from today. ATS with shadows to high. Maybe its LLVM?
Confirmed: Radeon HD 7850 kernel 4.14.13 mesa 17.3.2 LLVM 4.0.1
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...
This might be a dup of: https://bugs.freedesktop.org/show_bug.cgi?id=104190
I think it's not the same bug. CS:GO works on my system as it should, while SCS games still have broken shadows.
(In reply to Alex Vorobyev from comment #8) > 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.
Seems good now: Radeon HD 7850 kernel 4.16.3 mesa 18.0.1 LLVM 6.0.0
Can confirm that with LLVM 6 and Mesa 18.0.2 artifacts are gone. Marking this as resolved.
