Some elements are failing to display in ios8/8.1 
I noticed fixed headers were not being rendered in my application

I have tested it on the following.
- Does not render on all phones in the ios 8.1 simulator.
- Renders fine on all phones in the ios 7.1 simulator.
- Does not render on real iphone 5 (D654LL/A) with ios 8.1(12B411)
- Renders fine on real iphone 4 (MD146LL/A) with ios 7.1.2(11D257)

Here is a screen shot of the move finder example failing to render correctly.

The strangest thing is it renders ok when it is previewed between switching windows.

Any ideas?
