Pixel Perfect Camera not clearing screen that is cropped?

I have a pixel perfect camera using URP, and the cropped section of the screen is not cleared.

The pattern you see going around the view is the UI pointer. The cropped part of the view is not cleared, so the pointer is copy-pasted on top of itself over and over again as I move the pointer.
How do I make it clear the entire screen instead of simply what is inside the cropped view?

set the camera clera flags to skybox it worked for me
