Created attachment 1241982 [details] evemu-record output On libinput-1.5.0-1.fc25, everything is great. On libinput-1.5.901-1.fc25.x86_64 and libinput-1.5.902-1.fc25.x86_64, my cursor moves unusably slowly. This is on an X GNOME session. (I have no idea why X got chosen, and I can test Wayland too.) I've attached an evemu recording of myself moving my finger around the touchpad at moderate speed.
