--- Comment #9 from Michel Dänzer michel@daenzer.net --- Does running the affected apps with the environment variable RADEON_THREAD=0 work around the problem?
(In reply to Aaron B from comment #7)
I don't have bad rendering during normal renders like you guys, but when mousing over the bookmarks bar in chromium the overlayed boxes are usually corrupt for me now. R9 270X.
And that's caused by the same Git commit? I.e. if you revert that commit, the problem goes away?
