Vlad, thanks for the hint! The xdg-desktop-portal-gtk package was not installed on my Jammy test system. After installing it, all three remaing UI issues (wrong theme, wrong cursor, wrong font size) seem to be fixed!
So it would help, at least on Kubuntu, if the xdg-desktop-portal-gtk package was installed by default. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1959027 Title: [snap] Various UI and theming issues when running in Plasma Wayland session To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1959027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
