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.

It'd be great if others who are familiar with QuartzDebug could report if they 
are seeing the same
thing, I've never noticed this before and am quite surprised.
