Strange plotting issue after upgrading to AutoCAD 2015

[troll53]

After three days of scouring every source I can think of, I am turning to the community for help. Our firm recently upgraded computers and software, moving from Windows 7 machines running AutoCAD 2012 to new, Windows 10 computers and AutoCAD 2015. The issue we are having is that our logo on title blocks is not printing correctly. All fonts, lines, polylines, blocks, etc. print just fine, it is only our logo that goes awry. We print the stone age way, from model space using a full size drawing and scaling the title block up around it. (Please don't lecture me on this workflow, I did not put the policy in place I'm just trying to fix the problem.) The title block has our logo (a cad file consisting of solid hatches) x-referenced into it and that is then placed on the drawing 'sheet' as a block. I am including an image of what the logo looked like when plotted from AutoCAD 2012 and the after effects of plotting in the same manner from AutoCAD 2015. Any ideas are welcome.

Here is a plot image from 2012:

Well, if anyone here happens to run afoul of this problem, I had a conversation with Autodesk support today and we found that changing the 'shademode' to wireframe and then back to 2dwireframe cleared up the issue. Unfortunately, it has to be done in every-single-drawing... At least as far as I know it does. Would be great if there was a global fix.
