Is the UI freaking out on anyone?

Just logged in and my UI spazzed.

All my addons are disabled, have been for months now and I just use Blizzards standard UI.
I log in and it’s giving me some weird UI setup so I change it and then it spazzes, showing ghost boxes in upper left hand corner of screen and nothing else so I close down and open the game again, log in and select the right UI.

So far it’s okay but was just wondering, anyone else having this odd thing happen?
