I’ve been facing an issue when filling PDF forms in Okular for a while now: I check a checkbox and the mark is only visible while I’m in form filling mode. As soon as I quit this mode, the checkbox appears empty again.
My first comment there links to a pdf you can easily download to reproduce the problem.
Also, a recent reply in that bug made me try the flatpak version of Okular, which works fine (!) and pointed at a potential issue with the distro-provided package (Okular or libpoppler).
Is anybody else facing this on TW KDE? If so I guess I’ll open a bugreport.
Thanks, tried that but still see the issue.
The new user account has of course none of my main user-level fonts installed, and uses KDE defaults as shipped by opensuse.
So if it’s somehow font related, it might be caused by a font I installed system-wide, otherwise I suspect it’s rather an issue with the tumbleweed packages (either okular or libpoppler or some other dependency).
I usually update with sudo zypper dup, and occasionally via Discover (to take care of flatpaks).
