There is a particular landing animation that appears to be bugged resulting in a harsh snappy movement where the character snaps his upper body back up after landing looking very un natural and snappy. Similarly to the snappy pop (foot clipping through board) bug I posted previously this one also came with S3 and became more frequent with S4.
To me it looks like a normal animation but unintentionally sped up dramatically. I find it happens more frequent when doing a trick up something like a ledge but it does happen just about everywhere including landing into transition.
Attached are numerous examples including one that appears to be the proper animation the way its intended.
