I feel like pinch zoom in 3.x was smoother than in 4.x. Are you folk seeing this as well or is it just me? Just try the 3.x sample vs. the 4.x on a device. It seems the zoom levels in 3.x are more "spaced out" than in 4.x. I also see white lines that seem to outline tiles in 4.x. Seems like the map is rendering as the zoom in/out action is taking place. In 3.x looks like it renders after the zoom in/out action is complete.
Is there a way to make 4.3 pinch zoom like 3.x?
