I've got the same problem - I'll select something like information on/off or shuffle on/off and the display won't update with the new setting. I can tell it's on from the way the unit it acting but it's there.
I've also had times where the display seems to lock in a certain state when changing the volume - I'll finish changing the volume and the volume display won't go away. Haven't been able to replicate it reliable but it has happened about three times in the past few days...
