I started xpinut to show the events, the attached is a series of events
when this jump happens (around the last 5 or 10 events, it's very
difficult to pinpoint the exact place).
The command I used is:
xinput --test "SynPS/2 Synaptics TouchPad"

Title:
Mouse pointer shows to the bottom on the screen on some pad touchs
Status in linux package in Ubuntu:
Confirmed
Bug description:
When using normally the touchpad, sometimes it jumps to (mostly) the
bottom of the screen. It jumps to any position in the bottom, not the
corners.
Also, sometimes it jumps to the top. This is not random jumping, or
erratic movement. It jumps to the bottom on some touchs.
I found that it's quite reproducible if you play a little with two
fingers on the pad, not moving the pointer but just touching the pad
with one finger, then with the other, then with the first, etc, in
rapid succession.
I'm happy to help with any debugging.
