You need to get the sources of plasma-desktop, apply the patch (patch -p1 < path/to/patch.diff) and rebuild at least kcms/kfontinst.
If you've no experience with compilation, you can ask your distro to pre-pick the patch (ask implies the answer may be "no") There's no schedule on when this patch hits downstream, sorry. It's not even applied upstream yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1437260 Title: Plasma5 Font Preview is not visible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plasma-desktop/+bug/1437260/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
