Hello. Today i'm logged into beta to develop some addons, and what i've seen on my 'old-ui' character:
Please note that i have latest oUF from github, and screenshot taken from my old UI, just ported to 5.x (currently i'm in process of development of new UI from scratch).
Interesting fact : player frame have no troubles at all, it's on target (didn't test more)
I think Blizzard changed some code for models...
