I determined this isn't the User32 cursor stuff. It's probably a D3D
surface with incorrect properties.
Can anyone recommend an OpenGL debugger or other mechanism for exploring
the surfaces of a given scene and playing with their properties? My
guess is the tools are pretty primitive for this kind of thing.
