Cape Rendering while under Speed effect

[minerguy341]

Cape stretches more than it should and loses coloration, turning white. as I'm typing this report, leaving the world and rejoining to see if it fixes it does restore coloration but now my player model fails to render at all

Running around in singleplayer, may work on servers too, while under speed potion effect greater than 2.
