The video has too little information but I am going to take a wild guess and say that you are using depth sorting in a group layer to do the layer ordering?

If so, sometimes layers will "flicker" like that when there is depth sorting by true distance and the layer gets close to order change and sort flickers. Just guessing. Can't help without the file or seeing how it's constructed.

Ha! Simple fix, but I will let you handle it.

The jittering is caused by the layer order key frames!!!

In your file you have layer order keys on frame 1 and 2. Frame 1 the arm with the flicker (your right, character's left arm) is on top, frame 2 that arm is behind. On the LAST frame the layer order key has the arm BEHIND. When it loops to the start you get 3 keys next to each other "flickering" the layer order of the arm back and forth. If you want this to loop smoothly make sure your key frames match up on the last and first key frames. I would suggest just eliminating the frame 1 key as it isn't needed or if it is needed just put the right arm behind the torso to match the other keys.
