One of my internal doors slowly swings fully open unless it's latched

brass hinges.

A spirit level shows that the door frame on the hinge side is
vertical, and the hinge side of the door is vertical as well. A plumb
bob made from a nut&bolt on a piece of string shows that the two
hinges are in line vertically.

Any ideas on what could be causing this?

Gravitational anomaly.

Indeed. Or it could be related to the fact that the north magnetic pole is leaving Canada and moving towards Siberia. Are there any iron or steel fixing on the door, and if so is it moving in the general direction of Siberia?
