When you change windows/move a window or several other cases the window which you painted on is partialy erased (The computer don't save all the windows graphics in memory). This means you have to paint your window each time an event like that happens. That Event's name is OnPaint - you must use that Event. Your PC and configuration regarding this problem are 100% OK.
