Hard to reproduce, but mostly happens when I use my middle finger to

Hi,
I have the exact same problem on a Dell XPS 13. 1 out of 20-40 clicks on
the touchpad result a pointer jump and a "random" click.
It's very annoying.

just made an observation, it happens when I use my middle finger to move
the mouse and click with index finger. Sometimes the double touch of
middle/index finger is interpreted as mouse move, the jump is more or

position .

This bug is very similar to this:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/365943
I managed to reproduce as described in bug 365943, however it takes
20-30 tries.
Original i thought it was due to clicking but not,it's just multi touch
bug/regression
New steps
yakkety comes with /usr/share/X11/xorg.conf.d/51-synaptics-quirks.conf
which has Option JumpyCursorThreshold in it .
So I tried playing with various values but had no luck.
Also
synclient JumpyCursorThreshold=10
Returns Unknown parameter JumpyCursorThreshold
Does anyone know why this parameter
Since the original bug report I updated to latest bios 1.4.10

synclient -l does not return the JumpyCursorThreshold :(
Tested it with final 4.9 kernel and bug still exists
