      Description

      I've just done a first evaluation with Qt 6 (6.2.2) and was thrilled to see that https://bugreports.qt.io/browse/QTBUG-56075 is fixed, well, or at least improved a lot.

      However, it still doesn't really feel as good, especially on short lists and I've noticed that this seems to be the fault of the overshoot feature:

      While the scrolling with the two fingers on a touchpad itself seems to be fixed (as in, it doesn't scroll at full speed on a single "wheel click" as it used to be), the overshooting still seems to show the old behavior.

      To reproduce, create a Flickable where contentHeight is 1.5 * the height, then use a touchpad (Linux/X11 at least, not sure about others) to scroll it at low-medium speed. Once it reaches the end, the overshoot causes a big and fast jump and then pulls it back, as it you would have hit the edge at full speed.

      This makes it still very odd to use with a touchpad.
