Hardware: touchpad issues with "edge scroll" on Gnome

[yusssufff]

Hi!
So here my touchapad has some problem with Mocaccino.
I use Mocaccino Gnome edition. Inside settings>touchpad, in Gnome, one can enable "edge scrolling".
Usually a very small portion of the touchpad on the right is doing the edge scroll.
But with Mocaccino half of the touchpad becomes dedicated to edgescroll.
That is too much space and makes that feature unusable.

I send you attached the info log from HWINFO.

Greetings and thanks.
