It is bug in MacOS Viewer too. I’m afraid nobody will correct it.

I have some closed rock borders that are opaque as expected when viewing

Okular and Atril.

Any suggestions on how to make them really opaque (on all PDF viewers)?


Translucency (which you only get on rock borders when using
"smooth-shading off"), does not work in all PDF viewers. There is
nothing you can do about that, unless you are able to submit a code
patch to the PDF viewer application.

Thanks for the info. I just opened a bug with poppler the PDF rendering library used in both okular and Atril.
