Created attachment 115071 [details] screenshot Search for "icons" KCM in the apps launcher and open it. "Get new themes" button is cut off as you can see in my screenshot.
Hmm, this is a QML KCM that doesn't seem to suffer from Bug 398820, but is still too small in a different way. Any ideas, Kai?

Feels like a bug in how the GridViewKCM automatically computes its minimum size. It isn't taking into account the button widths.
I can't reproduce this bug on Arch or Neon unstable edition. Operating System: Arch Linux KDE Plasma Version: 5.16.4 KDE Frameworks Version: 5.60.0 Qt Version: 5.13.0 Operating System: Ubuntu 18.04.3 LTS (Bionic Beaver) KDE Plasma Version: 5.16.80 KDE Frameworks Version: 5.61.0 Qt Version: 5.12.3
