Small camera distortion

Hi,

I have an animation of walking forward with root motion applied. The camera is attached to object “CameraRefractor” as it should be and then attached to CapsuleComponent.

While playing I can notice minor distortion in camera during the walk animation. It looks as if the camera was attached to the mesh and a socket, but it is not. In the blueprint there is no camera movement even though the mesh follows the animation.

What could be the reason for this?

There is no effect like this without root motion.
