Interesting bug ... but it is fixed now: The problem basically
was that the initial window was created by the generic screen
convert functions, but due to the machine switch, we finally ended
up the ST/STE screen convert functions here - and since the window
resolution stayed the same, Screen_SetSDLVideoSize() returned false
so that Screen_SetupRGBTable() was never called and thus Hatari only
rendered black pixels.
