[Zubersoft]

If you can send one of the PDFs to mike@zubersoft.com, I can send that PDF to the company that makes the PDF library. Version 3.8.17 is also waiting approval, so it would be good to verify the issue is still present with version 3.8.17. You can also go to Settings->Display Settings and switch the render preference from "Speed" to "Quality", or vice versa, which switches which PDF library is used. This may resolve the rendering issues you are seeing (which would make sense if it is set to "Speed" as I just updated that library with version 3.8.16 to get some bug fixes from the PDF library company).

Thanks,
Mike
