[Gameplay] Invisible Jinx Super Death Rocket

(I posted about this already, but forgot to give it the appropriate tag, and I couldn't figure out how to edit the title. I also found this bug applies to my opponents' super death rockets)

Every time I or someone else uses Jinx's R, the rocket is invisible to me, but visible to everyone else. EVERY SINGLE TIME. It's completely unplayable: I can hardly tell my ult triggered, and I can only tell hit or miss by if they go boom, and I can't get a better idea of speed of rocket, timing, etc., because I can't see the rocket at all. Then if I'm playing against Jinx, it's impossible to dodge the rocket when they fire it, because, once again, IT'S INVISIBLE, so I can't tell where it is. It's bad enough that I'm not playing Jinx again until it's fixed, and I pray that my opponents don't pick Jinx. After all, essentially not having your R is a huge drawback, and not being able to see your opponents finisher-skillshot is punishment. I always play on summoner's rift normal games (except for one URF, that was the first game I saw this bug), but since it happens EVERY time Jinx ults, I don't know of any more specific details on possible confounding interactions. I tried running a local data repair, but the bug persists.
