I can now see that another report has actually been reopened, so perhaps there is a newfound hope. Pls do try your best to push this fix into a near update, I love this game, but Java currently doesn't have this issue and my laptop can't really run it all that well, so this would be a blessing.
Another thing I noticed is with these fast movements, when in third person it will update later, which is what I think is happening here. If I turn at a high speed, my head will turn a good bit later.
I already have that turned off, and have had it turned off. I also have tried experimenting with the fps limit, it just seems like the arrow adjusts itself later than the player camera. What I propose is that it uses the invisible ray that each player has to detect where the arrow should be facing, because as it seems, it looks to only be keeping up with the arms.
This seriously is a pretty bad issue, especially relating to how bad projectiles work. Fast movements don't update fast enough which can cause inaccuracy when aiming with a bow or really anything else.
