Just to clarify. In my case, it is definitely not an issue with a single faulty controller. I tried 4 different controllers, 2 of which are brand new, with exactly the same problem. The 10% dead zone was the only thing I found that fixed it.

Had exactly the same issue. Flew the unmodified A320 since launch using the AP, with no problems. Then bam! After the patch before this one, it was unusable! As soon as I took off and engaged the AP it would bank fully to the right, and then fly circle patterns around the destination airport. Have tried everything, including increasing the dead zone on the controller to 6%. No joy. Then thanks to a comment on another thread tried 8%. I could engage AP again and it would stick to the flight path. A couple of times when altering course following the flight plan it would bank full to one side again, but I could correct it and immediately it would correct itself and rejoin the path. Trying 10% has ironed out those mid flight wobbles. So in my case, I had exactly what you were describing, and it was the controller causing it.
