And so it begins again.

Maybe the problem is obvious to you guys but it is not to me. Any help would be great.

Are you doing anything during the drawing that calls -setNeedsDisplay: or otherwise makes the view hierarchy think that regions have been invalidated?

The actual bug may not be in LNTab3View's -drawRect:. That particular method may just be a symptom. The actual cause might be something somewhere that is invalidating the drawing during the view hierarchy refresh.

Explicit calls to -display could cause this, too.
