Have you tried recalibrating? Resetting sensitivity manually?
Yes, there are many "bugs" with controlers in the new patch. From minor difficulty to hard to setup.
I recommend you back up your settings folder in case something goes seriously wrong. Then take a little time playing around with the Joystick setup and settings, see if you can get it to work. The problems/fixes seem to be pretty much individual, depending on hardware, Joystick, drivers, settings etc etc....
