something non-white.

transparent actually white-out's the classic app beneath it?
I guess, for my purposes, I have to ask if it's a bug and if there is
any work-around or code to fix it?
I think this is behaving as designed. Classic uses unbuffered windows,
so it's not possible for the window server to make your window
transparent above them; there's no window buffer with which to
composite the transparent portions of your window.
