I’m raising this issue again because it’s still happening. Upon logging into today my entire UI has shifted itself down by about 50 pixels, cutting off my chat input box, and half of my bottom action bar. I’m not using any UI addons, and it was fine when I logged out last night. My drivers are updated, and I reset my UI the last time it happened and it didn’t help. I had to log off and restart the game several times to fix it.
