Interesting tech note about how 10.4 handles screen refreshes

It doesn't sound to me as though REALbasic needs to "handle" this
at all -- it is an automatic function of the OS.

Right, but the article gives guidance on the good and bad practices,
and I'm wondering if there are any tips that users should be aware
of, since RB doesn't handle everything for us.
I've designed some nice pretty user interfaces using RB that look
great under OS X, but look god awful under XP because of the lack of
double-buffering, so it's a concern.
My reading of the technote suggests that, under 10.4.4, the window
backing store buffer may not always flush to the screen when we
expect it to (or ask it to?).
Anyone out there have any realbasic programs that do a lot of window
updating, and care to comment on whether the performance or CPU usage
has changed with 10.4.4?
