If you heard about PoC||GTFO e-zine, you know that they're playing
with produced PDF format a lot, keeping it still a valid. Since
zathura based on poppler, I've checked also those files with evince.
Seems evince parse them properly.
Take e.g. this file https://www.alchemistowl.org/pocorgtfo/pocorgtfo11.pdf
Zathura show nothing, evince show all pages properly.
You also can check on other files from this page too:
