Mouse & Keyboard unusable, after using controller

After you use a controller midgame, the Mouse Controlls are Broken, until you switch off the  Controller.

To reproduce this Bug, turn the Controller on,  move arround, and then switch back to Mouse and Keyboard.
The Movement will flick from the Sky, to the Ground, from left to right. Completly unplayable.
When you turn off the Controller, it works again.

In previous Battlefield Games, switching the Controlls back and forth midgame worked. I always fly with a controller.
