I have found that any of the following operations at runtime will
cause almost the entire window
contents to be drawn to screen again for no reason:
* toggling a control's visibility
* altering an editfield's Text property
* using RefreshRect, even on empty portions of the window
I discovered this using while Quartz Debug to optimize my program.
I then wrote an isolated test
project (and compiled it) and discovered the above operations
caused the behavior.

I reported huge amounts of wasted CPU cycles at least 8 month ago. In
my case,
RB wasted more than 30% for various controls - you know, 30% wast of all
available CPU speed.
