Comment # 24 on bug 920792 from Felix Miata

Changing this from 13.2 to 42.1, since a 42.1 bug was duped to this.

On fresh TW installation my systemsettings and menu icons disappeared, maybe by
coincidence, after switching from Breeze to Oxygen in various places in desktop
settings.

# rpm -qa | grep oxygen
oxygen5-icon-theme-5.30.0-1.1.noarch
oxygen5-sounds-5.9.0-1.1.x86_64
oxygen5-style-5.9.0-1.1.x86_64
plasma-theme-oxygen-16.12.1-2.1.x86_64
Out of habit because of too small YaST text I also had qt5ct-0.29.1.1
installed. Removing it only restored most icons, not all. I need qt5ct back
because all the descriptive text in YaST2 is too tiny. Installing qt5ct
shouldn't destroy the desktop this way.
