Hi folks,

I was able to alleviate this issue to a large degree by the following
change:

edit /usr/lib/X11/xorg.conf.d/10-synaptics.conf

add the line:

        Option "JumpyCursorThreshold" "90"

to the area starting with:

Section "InputClass"
        Identifier "touchpad catchall"


I still get a few jumps (but a lot less, and they are short jumps (apparently below the threshold)). Probably that value of 90 could be reduced until it starts to affect regular movement.
