Started happening with the 10/10/17 update.
Just equip the skin, spawn in-game, start moving around, and your character model will start spazzing out.
Unfortunately it's not even funny just really annoying. (Other people can see the bug)
Post your PBE bug reports here: something not functioning as intended? Store is broken? A champion's ability is not working? etc
