Finally! I can reproduce this on a little netbook (Atom N270). Hmm, at least I could reproduce it once. I restarted compiz without unity and it went away. And even after rebooting I can't yet get the bug back :P
However from what I saw, I suspect the fix for bug 882531 might be the cause. And I can't see that feature being used in Unity so maybe it's safe to just try reverting the fix for bug 882531... ?
