I am working on a macbook pro with OS 11.1 and Layout 2021.
Part of the title block of the Layout pages I create includes a white circle that is laid on top of a black background. The white circle is a photoshop file that has a transparent background. In previous versions of Layout, when I exported to PDF, this worked fine. In 2021, instead of a white circle on a black background, the graphic becomes a solid white square. This happens when I choose File > Export > PDF. If, however, I create a PDF by doing File > Print > Save as PDF, the white circle on transparent background works just fine.
Why do transparent backgrounds get corrupted in “Export” but work OK in “Print?”
