Gameplay-Jinx Ultimate Visual Bug

For a few months, I have had this issue with Jinx's ultimate whether I play her, she is on the enemy team or my own. The visual rocket, seems to launch ahead of the character model and then appears to be ahead of where it should be. However, the invisible "real" rocket can hit, and travels normally, but just can't be seen.

SOMETIMES this issues occurs with Gnar's boomerang as well. But not always. I haven't noticed any other champion issues but I may very well suffer from those as well.

Last night I used the league repair tool, and then just reinstalled League of Legends. Made sure my graphics card drivers are up to date and optimized league on the graphics page.

I'm playing on windows 10, nvidia geforce gtx 650 ti.

I saw on the forums that a while ago jinx issues could be fixed by limiting the framerate. But that hasn't seemed to work for me either.

Just wondering if anyone has found a fix for this.
