I regularly use text background in my drawings. An issue I have is when I have text with a background that is on top of a solid hatch, the rectangle background will still hide the hatch, even when the text layer is frozen. When viewed in print preview, the hatch is solid - no white areas. When I export the drawing to a PDF, the hatch is solid - no white areas. Only when I plot to our plotter do I have the hatch issue.

Any help will be appreciated. Also, this happens to everyone in the office. We all use the same plotter and are all running 2015. It seems to have only started when we changed to 2015.
