STEPS TO REPRODUCE
1.  Download RISC-V ratified specs document from https://docs.riscv.org/reference/isa/_attachments/riscv-unprivileged.pdf
2. Open in okular

OBSERVED RESULT
Bizarre blank pages, sometimes words written at random locations but mostly blank.

Normal pdf view like in firefox [opened from file:/// not https://]. Document viewer on KDE also works fine with this pdf.
