Bug ID: 96908 Summary: [radeonsi] MSAA causes graphical artifacts Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: Platerx@gmail.com QA Contact: dri-devel@lists.freedesktop.org
Created attachment 125035 --> https://bugs.freedesktop.org/attachment.cgi?id=125035&action=edit 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.

--- Comment #4 from Nicolai Hähnle nhaehnle@gmail.com --- 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 from Nicolai Hähnle nhaehnle@gmail.com --- 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 from Nicolai Hähnle nhaehnle@gmail.com --- Never mind, I see them in Unigine Heaven on Polaris10 as well. Must be a recent regression.

--- Comment #7 from Andrey Vaynberger Platerx@gmail.com --- The apitrace of The Talos Principle: https://drive.google.com/open?id=0BzMT1H8Zl-hEeXBhSUxqQkM1dEk. Just in case.
