if you go into preferences, and set the board size,  it will change the
displayed board area. This is always rectangular, and its not just an
artifact of our rectangular displays, PCB treats the white space as board,
and will not render components off of it.

Outline is nothing more than a specially named layer  with a convention for
handling what would be copper or silk on any other layer.
