I have a Lenovo Thinkpad E431 with touchpad:
# Input device name: "SynPS/2 Synaptics TouchPad"
# Input device ID: bus 0x11 vendor 0x02 product 0x07 version 0x1b1
I find a pointer jump when lifting one finger after two-finger scrolling
particularly annoying. It is somewhat difficult to trigger but I managed to
find a way to reproduce it more easily. Move two fingers upwards very slowly
and lift middle finger in the way, sometimes the pointer jumps considerably
downwards.
The recording attached triggers the pointer jump 2 times.</pre>
