Tekken 6

I hope the legs glitching issue gets fixed some day. It isn't only distracting but it also affects gameplay since the hitboxes are connected to the bones, so if they shake too much kick-based moves will start missing the opponent.

I've also seen that the leg shaking appears to be related to the positions of the characters in the stage. If you choose a stage without walls (infinite) and start moving far from the starting position (while pushing the other character), the legs will shake more and more. If you turn back and return to the starting point they will shake less.
