https://bugs.kde.org/show_bug.cgi?id=504451 --- Comment #11 from Junfeng Qiao --- I have the same experience for many other (scientific PDFs with many symbols) PDFs, when hinting is enabled, symbols disappear. Naively I thought text hinting would be good and should be turned on. Is it possible to fix this bug, or at least show a warning in the settings tab? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=504451 --- Comment #8 from Jure Repinc --- I managed to reproduce the bug even with Flathub version, and also workaround the bug in the openSUSE version. It looks like the bug happens when I enable the "Enable text hinting" option in "Performance" section of Okular settings. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=504451 --- Comment #6 from Albert Astals Cid --- I'm 98% sure that /usr/share/fonts/truetype/Courier.ttf and /run/host/fonts/truetype/Courier.ttf are the same file. Anyhow, to me this means "this is a opensuse problem" if it works on the flathub version of okular. Not much we can really do here, i suggest you report this to opensuse. -- You are receiving this mail because: You are watching all bug changes.
