The bug in the NWN model viewer for instance is VERY strange. Basically there's
the main window and some opengl child window. Most of the time it is rendering
to the main window instead of the child window (the app is doing that!). When
you move the window very quickly you can get the app to draw to the child window
again. In some cases it stays at the child window. I have no idea what is going
on, for some reason the app is doing strange things.
