This bug really only crops up when the monster, or object (I've seen this happen with barrels), is basically standing right in front of you. We're talking inches of space. Probably the bounding boxes that register the monster is overlapping with where the attack originates from the bow, causing the arrow to shoot incorrectly. But that's just a guess.
All I'm saying is that this bug has been around for a very long time, and it's easy enough to avoid. I am glad it will be getting fixed soon though. I hope it comes with other archery improvements.
