wildfire zyra root bug

there is a bug that has been around for a very long time it happens to me and my friends alot.

whenever wildfire zyra uses her root it causes an extreme drop in fps i thought riot knew about it but from the ticket i sent in it seems they didnt know.

anyways hope it can get fixed i can sometimes get my teammate to not use the skin but sometimes people just dont care and you cant ask the enemy to not use it.
