While testing 2.99.903 I hit this bug, which isn't actually a regression since 2.21.14 at least, since I can only reproduce it on my sandybridge laptop, not on ivybridge or haswell.
So opening a html5 video from youtube with chromium and putting it fullscreen works fine. When I exit the fullscreen mode though, only the browser window contents are refreshed, everything else shows remnants of the video. Clicking on the desktop returns things to normal.
since it only happens on sandybridge (didn't test on gen4 yet, don't have gen5) I guess it's a driver bug.
