OVRCameraRig use per eye cameras changes scale

I'm working on a 3D image/video solution so I'm using the 'per eye camera' option in the OVR Camera Rig in Unity.  I noticed that if I toggle this setting on and off, the scale of the world is radical...

Update:

So I've found a fix, in OVRCameraRig.cs I changed 

if (!hmdPresent || monoscopic)
{
leftEyeAnchor.localPosition = centerEyeAnchor.localPosition;
rightEyeAnchor.localPosition = centerEyeAnchor.localPosition;
leftEyeAnchor.localRotation = centerEyeAnchor.localRotation;
rightEyeAnchor.localRotation = centerEyeAnchor.localRotation;
}
else
{
                leftEyeAnchor.localPosition = centerEyeAnchor.localPosition;
                rightEyeAnchor.localPosition = centerEyeAnchor.localPosition;
                leftEyeAnchor.localRotation = centerEyeAnchor.localRotation;
                rightEyeAnchor.localRotation = centerEyeAnchor.localRotation;

Vector3 leftEyePosition = Vector3.zero;
Vector3 rightEyePosition = Vector3.zero;
Quaternion leftEyeRotation = Quaternion.identity;
Quaternion rightEyeRotation = Quaternion.identity;

if (OVRNodeStateProperties.GetNodeStatePropertyVector3(Node.LeftEye, NodeStatePropertyType.Position, OVRPlugin.Node.EyeLeft, OVRPlugin.Step.Render, out leftEyePosition))
leftEyeAnchor.localPosition = leftEyePosition;
if (OVRNodeStateProperties.GetNodeStatePropertyVector3(Node.RightEye, NodeStatePropertyType.Position, OVRPlugin.Node.EyeRight, OVRPlugin.Step.Render, out rightEyePosition))
rightEyeAnchor.localPosition = rightEyePosition;
if (OVRNodeStateProperties.GetNodeStatePropertyQuaternion(Node.LeftEye, NodeStatePropertyType.Orientation, OVRPlugin.Node.EyeLeft, OVRPlugin.Step.Render, out leftEyeRotation))
leftEyeAnchor.localRotation = leftEyeRotation;
if (OVRNodeStateProperties.GetNodeStatePropertyQuaternion(Node.RightEye, NodeStatePropertyType.Orientation, OVRPlugin.Node.EyeRight, OVRPlugin.Step.Render, out rightEyeRotation))
rightEyeAnchor.localRotation = rightEyeRotation;
}
}

to this:

if (!hmdPresent || monoscopic)
{
leftEyeAnchor.localPosition = centerEyeAnchor.localPosition;
rightEyeAnchor.localPosition = centerEyeAnchor.localPosition;
leftEyeAnchor.localRotation = centerEyeAnchor.localRotation;
rightEyeAnchor.localRotation = centerEyeAnchor.localRotation;
}
else
{
                leftEyeAnchor.localPosition = centerEyeAnchor.localPosition;
                rightEyeAnchor.localPosition = centerEyeAnchor.localPosition;
                leftEyeAnchor.localRotation = centerEyeAnchor.localRotation;
                rightEyeAnchor.localRotation = centerEyeAnchor.localRotation;

/*
Vector3 leftEyePosition = Vector3.zero;
Vector3 rightEyePosition = Vector3.zero;
Quaternion leftEyeRotation = Quaternion.identity;
Quaternion rightEyeRotation = Quaternion.identity;

if (OVRNodeStateProperties.GetNodeStatePropertyVector3(Node.LeftEye, NodeStatePropertyType.Position, OVRPlugin.Node.EyeLeft, OVRPlugin.Step.Render, out leftEyePosition))
leftEyeAnchor.localPosition = leftEyePosition;
if (OVRNodeStateProperties.GetNodeStatePropertyVector3(Node.RightEye, NodeStatePropertyType.Position, OVRPlugin.Node.EyeRight, OVRPlugin.Step.Render, out rightEyePosition))
rightEyeAnchor.localPosition = rightEyePosition;
if (OVRNodeStateProperties.GetNodeStatePropertyQuaternion(Node.LeftEye, NodeStatePropertyType.Orientation, OVRPlugin.Node.EyeLeft, OVRPlugin.Step.Render, out leftEyeRotation))
leftEyeAnchor.localRotation = leftEyeRotation;
if (OVRNodeStateProperties.GetNodeStatePropertyQuaternion(Node.RightEye, NodeStatePropertyType.Orientation, OVRPlugin.Node.EyeRight, OVRPlugin.Step.Render, out rightEyeRotation))
rightEyeAnchor.localRotation = rightEyeRotation;
*/
}
}

basically making the left and right camera do this

leftEyeAnchor.localPosition = centerEyeAnchor.localPosition;
rightEyeAnchor.localPosition = centerEyeAnchor.localPosition;
leftEyeAnchor.localRotation = centerEyeAnchor.localRotation;
rightEyeAnchor.localRotation = centerEyeAnchor.localRotation;

seems to work :)

Thanks for this workaround! It's a strange issue, still occurring in2020.3.30f1.
