Window is too small as you can see in my screenshot.

Not a QML KCM, so probably its sizeHint is too low.
It computes the sizeHint from the first (default) page. It would need to go through all pages and use QSize::expandedTo() with the sizeHint for each of them.

Fix Default Applications KCM window size
Config widgets were loading in when a service item was clicked.
This change loads all config widgets at the start so the window can be sized to the largest widget.
