@Jeremy Huddleston, I see you are right, apologies (except that the fix appeared only in Unity-3D, it was worse in Unity-2D than it was before Unity-2D appeared). Does Xubuntu use Metacity? If not then my point is still valid, that it would be best to file a new bug for Xubuntu if the problem exists there, describing in detail exactly what the problem is.
