On Oct 25th 2012 I posted about this. I finally got around to digging into what the cause was and have now got my app working correctly (or at least the way I want it to).
In summary it was all related to saving and restoring the graphic context correctly in -drawRect. In my case I use a number of gradients as well a bezier paths and the crucial thing was to understand just where and when to save/restore the context. None of the tools available were of much use, nor was output in the debugger, either console, stack, or variables. It came down to good old-fashioned slicing drawRect till I discovered the cause. So I'm very glad the problem occurred and forced me to research it. I learned a great deal and as the saying goes "K is P".
