Change to orbit function?

This is what I see when orbiting in that model.

Thats what I would call normal orbiting behaviour. However I have come across an inconsistency where the arc of the orbit changes noticeably like its picked a point much further away and the arc increases a lot.

As i mentioned earlier it was difficult to reproduce and i should image its a minor localised issue.

I got the most amount of repeatability when orbiting around these areas.

I tried with the cursor in those spots and still can’t reproduce it. Maybe someone else can.
