Hello, bascially, this has been happening i think when the fps is below 60 fps as I have the same issue in the league of legends loading screen where i can see the shadowing of the mouse when i move it. but then goes normal when i get ingame. But this problem has been more annoying recently as ive been playing new world. When I move my mouse to look around, the brightness goes slightly up causing this flickering effect, and black shadows left behind objects in game. I can fix it by turning my monitors adaptive sync off and on again, but I'd rather just fix the issue here. Ive also tried pendulum, changing the fps and again its the same, anything above 60 fps looks great, anything below looks awful and the shadowing appears.
