What do you want to do? You could for example install the main window as an event filter on the child window and catch QEvent::Move.

The underlying window system will send paint events when a window underneath is exposed. You must be doing something weird. Do you have any custom widgets in your main window that show this garbage? Could we see the slot that is connected to the button?
