I believe I have the issue described in comment #15 for the X230, on my Lenovo IdeaPad Z710.

With a steady finger drag the cursor will move very slightly for a couple pixels before quickly shifting forward a couple pixels, such that at first I believed that the cursor was merely snapping to each line of text.

The settings in comment i#15 are a fix because the problem does not occur with the AccelerationProfile set to 2, but it is imperfect because I prefer the other acceleration profile. Changing only the acceleration profile to 4 and the constant deceleration to 3 also works, depending on how you like your cursor.

It is difficult to tell which other acceleration profiles have the problem, but it may also occur in 3.
