Comment 3 for bug 1177632

> So working around the bug would kind of defeat the purpose of testing.

Well, in your original description you raise the issue that this leads to difficulties to get correct datas, so I thought you might want to be able to filter out a known issue... anyway that seems like a compiz issue, there had been similar bugs on some videocard in the past (bugs in the videodrivers), can you reproduce on real hardware (that would help to determine if that's indeed dependant of the video driver)
