I don't think that'll work, because ScrollWindowEx doesn't take into
account obscured parts of the window. It only invalidates the parts
that will scroll from off-screen and need to be redrawn.

Is there a mainloop event that tells you a window is being obscured?
It could be recorded and used later.
