I feel like I need to clarify, since reading #2 again I'm kinda not even really understanding what I said. So! I'm speaking about the main character, who is generally the center of the frame, but as the camera pans in whatever direction you're moving, his sprite specifically begins to jitter as the camera attempts to re-center on him, I guess is the best way to put it. I'd expect the camera to pan smoothly and his sprite to not be jittery, but he's very jittery as you move about. Everything else seems okay.
