ok, in my case it seems to have indeed been a specific application. I killed it - CPU usage was back to normal. Memory was not freed though. I am not sure if this application hasn't been updated between 11.10 and 12.04, so I cannot say if a change in xorg or a change in teh application caused it though. (I was finally so frustrated I started killing apps when I found it...)
