Why are unconnected portals not rendered properly within the portal view?

This is actually the “expected” behavior for this system. A portal can’t properly render another portal that isn’t linked. Supporting this would require portals to be aware of all cameras and portal views from all unconnected portals that could possibly be within the portal view. With recursive rendering, this becomes even more complex since it could involve combining multiple cameras at once. Currently I don’t see any way on how to implement this behavior.

Screen position out of view frustum error. How to get rid of it?

I already added some code to minimize this issue, but it can still occasionally occur.

Don’t worry. While it can be a bit annoying, it doesn’t actually affect or “break” the portal view. If I find a proper fix, I’ll include it in a future update of the package.

In the meantime, you can simply disable “Error Pause” in the Unity Console to prevent the editor from stopping when the message appears. You can safely ignore the error while testing in Play Mode.
