Pspace Polygon Vports Not Shown Correctly

Hi,

When ever I have a polygon paperspace vport that is placed on a layer that is turned off and I click to activate it, there is an incorrect outline of the polygon vport that shows up on the graphic screen.  This problem does not occur with rectangular pspace vports.

I'm experiencing this problem on both AutoCAD 2014 & 2015.  On AutoCAD 2010, running the same hardware is fine.

I've tested this on both the following recommended graphics cards:

Card name: NVIDIA Quadro FX 4600 with 758 MB Ram
Driver version: 9.18.13.1106
Tuning Date: 3/24/2014
Virtual device: Dx9 (Hardware)
                The card and driver meets the recommended requirement.
Card name: NVIDIA Quadro 2000 with 1 GB Ram
Driver version: 9.18.13.1166
Tuning Date: 4/12/2014
Virtual device: Dx11 (Hardware)
                The card and driver meets the recommended
