Well all they needed to do was erase the screen with white and draw on it, but their app's internal logic meant that they erased it more than once.
I was capturing QuickDraw library calls - the low level graphics primitives, to figure out where the graphics time in apps was going and found out sometimes excel did it 9 times
Of course users didn't see it more than once, but our hardware made all that wasted time run faster
