Probably better to open a new one.

I think what happens is that the blit is rejected because it's partialy outside
the screen. While moving the window to the outside that isn't very noticeable,
but as soon as you move it back you see the now cleared parts of the window
that don't get updated untill the window is fully inside the screen again.
