Yeah, that's right.  Doesn't do it on the hardware though, so not really a 
problem.
I assume it's due to a difference in z buffer precision on the simulator vs. 
the hardware.

Flickering was observed on IPad 2 also. When the offset and helght for the 
label properties were increased the flickering stopped.

Depending on how far out you are, you might need to move the drawOffset up a 
bit.
