The report in question is (was?) about the gallium radeon driver - r600g.

On the classic radeon/r200 front there was a regression caused by commit 779cabfc7d022de8b7b9bc7fdac0caffa8646c51 (which itself fixing some BE issues, circa 11.0), which was resolved in 11.0.6 and 11.1.0. If things are still off, then I'd suggest opening separate bug report and if possible bisecting it down.
