The Tiled View visibly reloads it's tiles when the application is switched from background to active?

It also appears to happen when the app is left inactive for a period of time.

I do notice this, I'm assuming it's a memory issue with the device. It might be necessary to add some level of caching so refreshing the tiled view doesn't cause this annoying behaviour.

I'm looking into this, it seems like capturing a CATiledLayer's in a graphics context is a bit difficult. see https://github.com/incanus/TiledLayerSnapTest and related links. I'll continue to look into this.
