Syndra Ultimate FPS Bug on Cameralock

There is a bug on Syndra's ultimate, where it will make your FPS stutter if you have camera lock on until your ultimate orbs disappear. This is a bug that has existed since 2014, and I wonder why Riot has not fixed this yet.

This bug has existed for at least 3 years, which is pretty ridiculous.
