Short description of error
Motion blur jitters in the viewport when using a "Follow Path" constraint on the Camera.
Adversly, parenting the camera to an empty produces no motion blur as Eevee doesn't recognize the camera as moving.

Exact steps for others to reproduce the error
Set camera to follow path, go to camera view.
Switch on motion blur in Eevee settings.
