While this was fixed in upstream libinput 1.11, 1.12 managed to break it again. https://gitlab.freedesktop.org/libinput/libinput/issues/148#note_36487 For now, the workaround is to comment out the "Latitude E7470 Trackpoint" section in /usr/share/libinput-1.12.0/libinput/50-system-dell.quirks, or to set the "AttrTrackpointMultiplier" value to a lower value (e.g. 0.125) in that section.
