Can somebody please give a hint on what those remnants are in the mdi area 
when QDockWidget/QWidget::move() is called? There are no such artefacts when 
the dock widget is resized manually. Can we set the color of this area to the 
color of the mdi area? Or is there simply a repaint/update missing somewhere? 

Thanks and Regards,
