Please note that, at least for some applications, it might take a few window manipulations, including all of resize/minimize/restore in order to trigger the bug. So Alexandre might not be trying hard enough.
Actually I haven't tried at all with metacity, Dmitry was probably confusing this with another bug. I'll try it when I have a moment.
