Despite MC-277517 having been declared fixed, the issue still persists, albeit in slightly different form.

Steps to reproduce:

1. Build two towers two blocks tall with a distance of two blocks in between.
2. Position yourself against the approximate middle of the one tower, facing the other.
3. Aim at the middle of the upper edge of the tower you are facing.
4. Shoot arrows at the target until you get a good picture.
5. Repeat this process in 1.21.1.
6. The arrow patterns produced in each version differ significantly: The arrow pattern in the newest Pre-Releases exhibits up to four slightly offset spots where the arrows land, and they also land lower than they would in 1.21.1.
