Pixelated DOF issue on out of focus objects close to the camera when rendering through Movie Render Queue. (UE 5.6)

Turn off Enable Alpha Channel Support in Post Processing(Experimental) in 5.5 below. Turn off Alpha Output in 5.5 above is my answer. Not an Nvidia issue, more of an implementation issue for UE5 i think.
