description:
there is a "death" trackpad area for the cursor movement. This issue happens
only when I _start_ a movement, that is I place my finger on the "death" area
and then I start moving it. This is not an issue if I continue the movement
over that area because there is no problem, it is recognized as active and the
cursor keeps on its movement.

evemu, attached. I have recorded a one-finger horizontal motion: I put the
finger outside the trackpad, on the left and at the middle of its height. I
have started a horizontal motion to the right, covering the piece of case, then
I entered in the trackpad area(*) up to the center of it. Finally I came back
up to the original starting point. What was the goal of this movement: show you
that for the outward path, there is a "death" area: cursor starts its movement
one centimeter after my finger entered the trackpad area; while in the return
path the cursor keeps on going until my finger goes out of the trackpad area.
