GTA V has an odd depth buffer for which the usual depth linearizing function doesn't quite work. If the minimap is enabled, the depth buffer ReShade takes is one with a white rectangle on the left lower corner but if you disable the HUD, this rectangle is gone. We are currently trying to find a proper function to use the depth buffer, Crosire came up with one but for me, it loses all accuracy in the area of 10m and closer so DOF and AO have strong bugs in this area.
