We've already been doing this for semi-mt devices and for non-clickpads but let's do it for clickpads as well. On Synaptics touchpads (PS/2 and RMI4) we see slot jumps where two slots are active, slot X ends but slot Y continues with the other slot's positional data. This causes a cursor jump on finger lift after a two-finger scrolling motion. Simply resetting the motion history fixes it. The only multi-finger interaction where a user could expect perfect fluid motion is when using a second finger to touch cone of the software button areas. Let's see if we have complaints first before we implement something more complex. https://bugs.freedesktop.org/show_bug.cgi?id=91695 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com> (cherry picked from commit aa87d2b2)
