I have tested a project that makes use of a QML ListView. Scrolling with a trackpad works, but it is way too fast and it is impossible to scroll the list by a small amount. The speed of scrolling is certainly way too high. No problems occurs when using touch to scroll the list.
For example, in the Qt Quick Controls 2 Gallery example, attempting to drag a bit in the drawer list to see what is available triggers a flick that scrolls all the way to the other end of the list.
