Camera flicking back and forth with more than 1 touch point

This issue started occurring for me at 1.2.6 after I updated my Pixel XL to Android 8.1.

In short, when touch controls are used (I use left thumb on d-pad and right thumb to turn) the camera flicks rapidly back and forth. This issue is extremely irritating to the point of making the game unplayable.

The attached video may better explain the issue.
