Visual Problem With Yorick

I play Yorick on the regular and I usually use his Undertaker skin, although as of late I've been using all of his skins from Pentakill to his classic, but when I was playing with his classic I noticed that walking just normally back to top lane his right arm was constantly going through the stone on his back. It was bugging me, and then I wanted to see if it happened on his other skins, and yes it was doing the same thing on Undertaker too as well as Pentakill, Pentakill not being as bad though. I'm just curious if it could get fixed or not. I love playing Yorick, he's definitely my one favorite champs in league and I'd like to see his arm not going in and out of the stone. Thank you.
