Low resolution creates strange unwanted camera effect. It's not fog.

Fog is disabled. This is a project using the "3D With Extras" template. This happens when post processing is on or off. I know that its a blending issue with non-solid r, g or b colors, but only happens at a distance. Depending on the resolution of the image, this effect will show closer or further. Attatched is a screenshot of the lowest resolution of the scene I have, the "camera preview" in the corner. I have a large 21:9 monitor 2560x1080 (i think)

 

Played around with quality settings. Shadow cascades seems to be the issue. I don't know what this is and feel it would break the look of a game if i turn it off. Please help <3 any words appreciated

 

This is shadow acne from the main directional light's shadow cascades. Increase the bias setting on the main directional light.

 

Thanks! I stayed away from that because it messed up shadows, but increasing just by 0.1 worked just fine
