Question touchpad double tap keeps very slightly (2mm) up and down while keeping my fingers on without moving them at all ?

touchpad double tap keeps very slightly (2mm) up and down while keeping my fingers on without moving them at all! Like when you scroll using both your fingers the page scrolls up or down as usual, BUT when you stop moving your fingers the page keeps shaking very slightly (few mm) up and down in a very annoying way and I have to take my fingers off the pad in order to stop this shaky behavior. the laptop is brand new out of the box with all recent updates but the issue persists! any suggestion?

updating all drivers. decreasing touchpad sensitivity, decreasing cursor speed.......none has worked!

in touchpoud settings there should be touchpad sensitivity, adjust that
