Canvas scaling on 4k monitors

Does the canvas output from Animate CC automaticlly scale the canvas on 4k monitors? I have a project that it seems is reporting:

Normal monitors: stage.scaleX: 1

4k monitors: stage.scaleX: 2

This seems crazy because if you scale the canvas then the coordinate system gets messed up, which is happening in my project.  When I try to use event.stageX the positioning value is way off.
