Dear friends,
Over the past few months, I have noticed that some PDF documents do not render on Fedora 36 using zathura, evince or okular. The PDF document, however renders fine on my phone. All of them are PDF, version 1.5, and they were sent to me by email, which I read using mutt.
What could be wrong and how could I trouble-shoot/fix this? Note that I can read many other PDFs using the same mailer, so there is something different with some PDFs (received by email) and read by using mutt.
Many thanks and best wishes, Ranjan
