artifacts in The Talos Principle
Artifacts in Unigine Heaven
Description Andrey Vaynberger 2016-07-12 20:26:03 UTC
Created attachment 125035 [details] artifacts in The Talos Principle When I enable MSAA (x2, x4 or x8) in the Unigine Heaven or in The Talos Principle (I haven't tried other games yet) I get graphical artifacts. You can see them on the attached screenshots. GPU: AMD RX480 OS: Fedora 25 Mesa version: git b479c47 LLVM version: svn 275001 Kernel version: 4.7.0-rc6 linux-firmware: git a141500

Hi Andrey, thanks for the report. I just tried Unigine Heaven with x8 on Tonga, and see no such problems. I'm also fairly certain that I tried MSAA in Heaven on Polaris10 and so no such problems, but I'll re-try when I get the change. I'll keep you posted.
Comment 5 Nicolai Hähnle 2016-07-13 09:07:10 UTC
Sorry, forgot to mention: could you provide an apitrace of The Talos Principle that shows the artifacts on your system? Upload e.g. to Google Drive since it's going to be fairly large.
Comment 6 Nicolai Hähnle 2016-07-13 09:26:00 UTC
Never mind, I see them in Unigine Heaven on Polaris10 as well. Must be a recent regression.
Comment 7 Andrey Vaynberger 2016-07-13 19:20:46 UTC
The apitrace of The Talos Principle: https://drive.google.com/open?id=0BzMT1H8Zl-hEeXBhSUxqQkM1dEk. Just in case.

The patch at https://patchwork.freedesktop.org/patch/99101/ fixes the problem for me.
Comment 9 Andrey Vaynberger 2016-07-17 18:09:21 UTC
I confirm. The patch fixes the problem for me as well.
