** Description changed: When scrolling anywhere using 2 fingers the scroll bounces back if fingers are lifted up from touchpad. Soft finger point muscles have some flex to them and I strongly believe this causes the scroll bounce back. Easily repeated to both directions. In bounce scroll rapidly moves to the opposite direction of where user wanted to scroll when lifting up fingers. + + Attached is log file evtest_event5.log from single scroll where there + was bounce at lifting fingers.
