Camera not rendering while VR headset attached
I have a CameraController, that will activate the XR Rig's camera once an XR headset is detected. If no headset is detected, it will activate the "normal" camera. 
So, I'm in a situation where the normal camera is active and the VR camera is inactive. In the Scene view, I can see the output of the normal camera: 
The normal camera is set to output on Display 1. When I check the Game view (on Display 1) it just renders a black screen with UI on top. Note that when I turn off the normal camera, too, it would say "Display 1: No cameras rendering". So, it appears that the Game view understands that the normal camera is rendering to it, but it just won't show it.
Why won't my camera's result show in the Game view?
Here are the further settings for the normal camera:
