That's because the AES decided your window covered the whole screen,
and therefore your redraw would take care of everything, and it didn't
have to update anything.  The right way is to open a window just
the size and location of the logo.  Then that window will get redraw
messages when parts of it are exposed, and the Desktop background
will get redraw messages for the rest of the screen.
