Freeze moments and lock ups when you go into the items or Quest screen selections. It happens every other time. I dont know if actual bethesda developers peek in on the forums comments here like that but thats a patch i hope they send through after the holidays as an update on xboxlive. thats all i found wrong that hindered my gameplay experience
example: while fighting a dragon i was trying to switch back in and select items for energy and magic but the game locked up and blocked me away from getting the potion i needed so i had to hit the B button to back out twice and go back in when the bug passed. meanwhile the dragon was lighting me up because my react time to activing the potion was screwed.
bad situations like that i have a lot with the game. Other than the game is great
EDIT
I apologize moderator Sean. I see my bug report pretty much matches what you posted here
Menus:
-Can be extremely slow
-Lag when opening containers and inventories
So i guess the developers already know of my particular issue...
