Hi,

I have some issues with my Cyapa touchpad from my HP Falco with libinput driver
(no problem is present with synaptics driver). The cursor "jump" sometimes.
It's often when I want to make a click with the bottom left touchpad button.
Sometimes at the moment I touch the button the cursor jump at the bottom left
of the screen. Note that the button are "integrated" to the touchpad.

I'm running Fedora 23. Here is the output of "udevadm info
/sys/class/input/event8"

P: /devices/pci0000:00/0000:00:15.1/i2c-7/7-0067/input/input8/event8
