Using a SceneDepth post process blendable changes FOV?

I have put a post process material on a scenecapture component to get depth info, and I cant seem to figure out why its changing the scale/fov of the scenecapture.

Heres a picture showing what is happening:

The left is a color capture, the middle is the depth material, and the right is an overlay. Any way to fix/get around this?
