It happens when I have my HUD off or when I'm not in first person.

I tried using other shaders on their default settings but it still wouldn't let up.
I tried it on Complimentary, BSL, and Complimentary reimagined.
I found that the dots get more pronounced if I have PBR on.

I have the following installed:
rubidium-0.5.6
reforgium-1.18.2-1.0.12a
oculus-mc1.18.2-1.6.4
