The VisualEditor isn't perfectly rendering markup yet (which is understandable), and even when it does it'll look slightly different from read mode in a lot of ways. The problem is that cancelling the VE editing interface, or saving, loads a VE-rendered article view rather than what the article actually looks like. (sorry if this sounds nonsensical; it's difficult to explain at this end).
The example given at the enwiki feedback page was [[scaphoid fracture]]. Observe the spacing of infobox content, then enter and leave VE mode and notice the alteration.
I believe all of the changes for this has been merged and fixed some months ago; please correct if there are still issues.
