UI Elements Flickering/Animating/Rendering issue

[jaymutzafi]

Only issue I'm having with this is when switching between VCs the UL elements look like redrawing or animating. Text moves from zero size to it's proper size. Table rows unfold from zero height to their proper height, a button I rounded with corner radius turns visibly from a square to a circle, etc'.

Seems like an order of events sort of issue. Any idea why?
