Same problem with Fedora 22 and kde5 plasma 5: see this bug on fedora's bugzilla : https://bugzilla.redhat.com/show_bug.cgi?id=1208229
I have same result like attachment "kcmshell5 fontinst, messed up preview pane"
For info : --this bug is present with nvidia's drivers
--it's present with nouveau drivers, but if I uninstall xorg-x11-drv-nouveau, preview for fonts in system-settings work.
