I'm not sure if this a bug or a feature, at first I thought that I was getting sick because my screen kept getting stuck blurry, almost like it is out of focus. A few times I have spawned in fresh with a blurry screen.
Regardless, it seems that if my screen is blurry, no matter what the cause, if I go into video settings then back out without changing anything my visuals sharpen up to a normal state.
I don't know if this is a bug with the game glitching and blurring my screen, and me fixing it by going into settings, or if I am bypassing a intentional mechanic by using an exploit with the graphics settings. Without status indicators to show some type of effect that would cause my screen to become blurry I am in the dark on what exactly is bugged here.
My screen has become blurry when I have not had bleeding, hunger, thirst, or a reasonable source of illness however, so it may be simply a graphics issue. I will update with screenshots next time it happens.
