This happens because the tile matrix is changing while the pinch zoom is continuing.

I'm going to fix this by disabling updates to the backingstore tile matrix when backingstore updates are disabled. This will prevent changes to the tile matrix when we are in the middle of a pinch zoom which can cause checkebroard flickering.
