3D KML on iPad Pro: bug with the KML shape

[Brunim28]

In 3D, on a very specific zoom level, the shape on a building added from a KML acts like a "ghost shape". The shape moves when dragging the screen. Landscape or portrait mode doesn't change anything. It doen't concern any other zoom level on wich the KML stays at the right place.
