Hmmm, never seen this before... looks like some resize-event or widget updates get stuck in the middle and/or aren't triggered after the graphics are switched on again. I would probably need to catch the power-management events from Windows to "fix" it, but I actually tend to think that the bug is not in QMC2 but Qt.
