I've reproduced this in an updated kubuntu 20.04 vm. There are no journalctl logs made when I change the icon either.
Note that in the common gnome based Ubuntu, this is not an issue and any symbol can be set in charts. ** Changed in: libreoffice (Ubuntu) Status: New => Confirmed ** Tags added: rls-ff-incoming -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870627 Title: Cannot change symbols in charts in LibreOffice Calc 6.4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1870627/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
