--- Comment #17 from Kai kai@dev.carbon-project.org --- Happy tidings: with Mesa commit 88fea85f09 and LLVM SVN r222517 (see below for the full stack) I get a lot less visual corruption, than before, see https://imgur.com/a/8g3Sp. The Catalyst is still better because there aren't any black areas around the mountain ranges from the intro scene. But in the scene looking out on the palm trees, I'd say, Catalyst/fglrx and radeonsi are now on par.
Long story short: a lot better, but still ways to go. It looks like part of this bug was the same as the later reported bug 86432.
Let me know, if you need something else – like a new apitrace – to debug this.
