Preview PDF transparency bug?
As far as I can tell there is some kind of problem with the PREVIEW app with some kinds of PDF file. Transparent layers in some kinds of PDF file just come out as SOLID BLACK. This doesn't happen with other PDF programs. It's been this way since Capitan so maybe it's something unrelated to the O/S?
If you've heard of this before what PDF files are affected?
How can I effectively replace the preview app? What do you recommend? Adobe seems heavy and slow.
