This issue also reproduces on a different workstation with Fedora 22 and plasma-desktop-5.5.5-5.fc22.x86_64.
Still an issue today: That is, works fine within System Settings, but if Font Management is run from application launcher then minimized / maximized it will become corrupted and need to be forced to close.

As noted in duplicate Bug 385076, this affects every standalone KCM window and is a bug in kcmshell. I can reproduce it with: systemsettings 5.12.4 KDE Frameworks 5.44.0 Qt 5.9.4 (built against 5.9.4) (This is my first attempt at triaging, so please forgive me if I made a mistake.)

Is this still a bug? As I understand it, it's no longer possible to open a stand-alone KCM, it always opens with systemsettings
