Created attachment 123803 [details] evemu-record ouput for simple right-to-left pointer movement. After an upgrade to libinput 1.3.0 my Elantech trackpad (on an Asus UX305C) became very unresponsive and inaccurate - it takes serveral tries to get the pointer moving, as if it became "sticky" somehow. Reverting libinput to 1.2.4 fixes this issue and the trackpad works fluidly without any issues whatsoever.
