    Oh yeah, setting, e. g., client_side_graphics to FALSE in
winex11.drv when I am to emulate exclusive fullscreen mode does the
trick. Do you mean something like that?

    But it won't help my updated test program, which does not involve
any ddraw and seem to show that the window just gets WM_PAINT on
obscuring window move or delete on Windows. I don't have an example of a
real application depending exactly on it though.
