Thanks for reporting the issue upstream. Could you check if firefox prints any warning when showing the document, if started from a cmdline?
could you do $ journalctl -f display the pdf, and copy here any warning that could be displayed in the log? ** Also affects: firefox via https://bugzilla.mozilla.org/show_bug.cgi?id=1767925 Importance: Unknown Status: Unknown ** Changed in: firefox (Ubuntu) Importance: Undecided => High ** Changed in: firefox (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971608 Title: Firefox PDF font rendering is often messed up To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1971608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
