Default Manny Foot Jittering?

I have not, I have even made a new level. Simply placed a plane for the floor and a player start, but it still has this issue. Nothing is in the map… I have deleted or disabled collision for EVERYTHING that has it on the character besides his capsule collider that he needs to stand and not fall through the map in the first place… I would suspect things on the character, but it is always a diagnal strip of area on the map that is affected specifically… I don’t get it… T.T
