white semicircle at the bottom of the screen blinking wtf? (Dying Light 2: Stay Human)

I practically just started playing and noticed that at the bottom of the screen such a white semicircle is small, but it blinks like an infection. As soon as I noticed him, I can not calm down, attracts the eye, annoying. I climbed through the inventory, I couldn’t find anything like that, there is some kind of gre, I turned it on and off, with no effect. This is not a pathology of the screen, this semi-circle is not in the game menu, etc. Help, plz.
