bogus events after releasing the pad

When I use 2 finger scrolling/circular scrolling the scrolling continues after I get my finger of the pad.
When I check with synclient -m 1 I see the x coordinate and y coordinate reset to some fixed values. Also the "z" and "f" value change randomly.
The behaviour in an application is that it's scrolls random in the y-direction or continues scrolling
