massive (Spirit Guard) Udyr graphic bug. [Screenshots]

I was playing an ARAM as a graphic bug between our Udyr and Jinx occured. It was like that from almost the beginning of the game I think (first I didn't pay attention to this). Sometimes the front part of Renekton's blade was connected with Jinx aswell. Even when Jinx was dead the bug was present (Screen07, second pic). Both Udyr and Jinx had to be on the screen at the same time, otherwise it would not work. As we reached the inhibitor half of the screen was covered by that bug, but not everytime we got there, if I recall corectly. Other players had the bug too, so I wasn't the only one. The bug did not change anything in the gameplay itself but sometimes it was unplayable because of obvious reasons (third pic).

None of the players new something about this bug before or did this on purpose.

(I linked the pics aswell, but kinda messed up the order)

Hope Riot can fix this bug :)
