Character/Object Ghosting

So there’s either a bug or some weird setting in the Third Person template,which ghosts your character when moving the camera with the mouse. Is there something wrong with the motion blur? I don’t know.

It may caused by TemperalAA, exist in UE4 for a long time. Still no good solution. You can try to turn TemperalAA off to see if the ghost is gone.

Switching to FXAA helps a bit, but looks worse. Is there some other way to remove the ghosting? Or has Epic said anything about fixing this issue?
