Just tried it.
It does not solve the problem, but improves the situation a lot. Now, =20=

i can use the left-down part of the touchpad.

I looks like the lower part on the left of the trackpad responds =20
quite well.
The other parts produces mostly small random movements. Those =20
movements are mostly horizontal, or at least, the movements =20
horizontal amplitude is more important. There are also horizontal =20
jumps, but less frequent.

Thanks a lot for your work,
