Well, "mitigate" is the right word here and it certainly is much less
noticeable. Nevertheless, there is still some flicker in window
creation/destruction. I would suspect that this is simply in the nature
of X: to eliminate any flicker with window creation/destruction would
require a transaction model that asks the X server to redraw the entire
screen only once all windows have been repositioned, treating the
manipulation of multiple top-level windows as a single transaction. As
far as I understand it, that's simply not part of the X protocol.
