[Gameplay] Rek'Sai skin glitch!

On the Eternum Rek'Sai skin, especially when you're going down the Mid-lane, and you use your Ult, you can see her body spazzing out from beneath the ground. I love the skin, I love Rek'Sai, but, the glitch in itself is enough for me to not go about using it.

Anybody else seen this?
