I have had the exact same problem playing with 2 xbox 360 controllers on split screen. Scrolling in menus/inventory gets stuck going up/down/left/right. I know the physical controller sticks aren't stuck because it doesn't act as if the stick is being pushed in the map or in the game world.
It is only happening to the Player 1 controller. It eventually stops on its own but can take a long time. Makes it impossible to save or use hotbar skills as the selection scrolls faster and faster.
I'll try unplugging and replugging. On Windows 10 x64 with 2 USB xbox 360 controllers.
