Render View Edge Thickness

In Rhino 6, the render view edges seem to be slightly thicker than the same view in Rhino 5. I have attached a screen shot showing the side by side. Both have the edge thickness option set to 1, but in Rhino 6 it looks thicker. Is there a new property in Rhino 6 that is causing this?

Also, looks like all edges in Rhino 6 are just a tad thicker than Rhino 5, even in other views like shaded. Is this just the new Rhino 6 default setting? Is it related to Windows scaling?

Great. Works great.
