STEPS TO REPRODUCE 1. Quickly and strongly swipe the touchpad down when over the menus of System Settings. OBSERVED RESULT The scrolling stops when the fingers leave the touchpad, regardless of speed. EXPECTED RESULT Due to how touchpad works, letting it go after swiping should have an artificial inertia effect (smooth scrolling).

Hello and thanks for the report! Do you happen to have disabled animation globally on your system perhaps?
Created attachment 183763 [details] Animation settings. I don't think I've changed anything here.
Indeed it doesn't look to come from there. Putting this as confirmed for now
System Settings now has smooth scrolling for me in Plasma 6.4.4 Can anyone test it now?
What you're asking for is inertial scrolling, not smooth scrolling. See https://community.kde.org/Get_Involved/Design/Frequently_Discussed_Topics#Names_of_different_scrolling_effects We already implemented inertial scrolling systemwide in Frameworks 6.16 for everything that uses a QML scrollview. However I have seen some reports that it was broken until Frameworks 6.17. I can confirm it's working for me with 6.17 or later. Adding inertial scrolling to older QtWidgets-based pages is not feasible unfortunately.
