what is exactly the difference? Do you know whether that's something lacking in QtQuick?

The scroll distance. My mouse settings are "Scroll wheel scrolls by: 3 lines" in System Settings (the default), and in QWidget list views (even ones with complex arbitrary-height delegates instead of ones that map neatly to lines) this translates to a bigger delta than in the effects KCM list.

Cliff notes:

- Needs investigation what QWidget views actually do. I have a vague memory the style is involved to some degree too, but I'm not certain. And then investigation of the options for teaching QQC how to do it too.

- The user doesn't care what state upstream QQC is in, though, and shipping unfinished/broken basic settings UIs is not acceptable imho, so a workaround would need to be implemented if the Qt available at release time can't be fixed. Taking over wheel handling ourselves and multiplying http://doc-snapshot.qt-project.org/qt5-stable/qapplication.html#wheelScrollLines-prop by $ui_font_mHeight could be that, if it turns out that's basically what QWidget does.
