+++ This bug was initially created as a clone of Bug #507733 +++ STEPS TO REPRODUCE 1. Have an scrollable desktop, by having items beyond the screen size. 2. Quickly and strongly swipe the touchpad over the items off screen. 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).

I'm not sure this needs to be done separately from bug 507733, it might be done at the input level rather than for each settings area, but the developers will determine that

In 6.4.4 System Settings has smooth scrolling, but the Desktop's scrollbar remains being abnormally slow and without inertia/smooth scrolling.
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 Regardless, we're planning to remove the "scrollable desktop" feature as it causes an endless set of bugs and UX issues, so I don't see us adding new functionality to it, sorry.

It doesn't seem to mention the line-by-line scrolling that is done on Konsole.
That's the absence of smooth scrolling.
