I recently run into this wierd issue, whenever (not always) i use gimbal pitch button it also turns my drone around, at the same speed i try to look camera up/down.
Connect the drone to Assistant 2 on your computer where you will see the option to factory reset the drone - then update the firmware again and do the calibrations - if it still persists after doing all of that then I suggest either returning the drone to DJI for repairs/replacement or live with it if it doesn't affect the safety of the flight. Good luck
