To add info to this: I am able to enter cat's eye with this and it shows me the reticle, so it seems to be some kind of visual overlay that is messing up. It's only happening to me as some of my friends can play without issue, but I cannot fathom why this happens.
I thought it was because my monitor is extremely large, but going into windowed mode and adjusting the window size to sizes comparably to the monitors of my friends didn't change anything either - it seems like there is something that the game doesn't like about my PC or my graphics drivers. I am using AMD, so not sure if that would mess with this or not, but it's nevertheless pretty strange and frustrating.
After trying to ascertain why it is happening, it seems that maybe it's something related to looking at lights, like a lense flare messing up? Not sure what else it could be, but the most surefire way to avoid it is to look straight up for some reason.
