The arrow ONLY on certain holes, particularly on the new maps jitters around a bit, and in some cases limits how accurately you can aim.
In the 1st example, MWood hole 1 you can see it’s fine, then on hole 4 it’s jittery, in this case doesn’t effect much other then looking jittery, not a precise shot.
MWood holes 4 & 8 both jitter.
On nostalgia holes 1-9 it’s completely fine, but on 10-18 it’s jittery on all.
Particularly on hole 10 it hinders how much you can adjust the aim to go for the HIO since it’s very precise, there’s spots where you move the mouse 3 pixels… it does nothing, then 1 more it jumps 4 effectively removing the option to shoot those 3 pixels in the middle, and it happens consistently.
Unsure of how the mechanic works so I can’t speculate on causes, just know it only happens on some holes.
