Either this hasn't been fixed yet or there's another issue which hasn't been properly triaged yet. It occurs rather frequently, even inside the text box where I'm writing this comment right now. It's as if there's a hidden-but-always-on-top U-shaped window, but it could be a box as well. I wanted to make a screencast but I could only click the istanbul icon once. I think it's still recording. Anyway, I used a camera phone to record the attached video but I couldn't see it myself because of #327082. FGLRX is enabled.
