An error occurred in drawing the scene. Redrawing graphics is now stopped to
avoid a continuous stream of error messages. To restart graphics use the
command "graphics restart" after changing the settings that caused the error.

Cool to see someone is trying VR with a RealSense camera I guess to make augmented reality videos.

The error message is one I have seen recently during a multiperson VR meeting (no room camera, no realsense camera), that happened when somehow the Oculus runtime app went belly up. It was not sufficient to shutdown ChimeraX and SteamVR, I had to restart the Oculus app, then all worked correctly. Too bad no reporter email, because I was lucky to figure this out.

The texture format for the VR eye images is fixed so I don't see any way that the error message makes sense. ChimeraX did not hand off a different texture format. More likely the Oculus runtime decided it wouldn't accept any texture formats.
