For my Toshiba Satellite C650 running "synclient TouchpadOff=0" when the bug occurs, works. I have disabled the touchpad option "Disable touchpad while typing" and in the last 15 hours I did not get the bug any more, but it's not a good decision not to disable touchpad while typing as it's not a great pleasure to see your pointer moving on the screen while typing texts. In my case there were no "window strange movements".
