Cursor jumps around

Hi,

With MBPro TouchBar 15" bought in June 2018, I'm in the nightmare of the "cursor jump".

Apple changed top case (keyboard, trackpad, battery assembly) and motherboard.

No avail.

Exactly what is described here

On second repair, machine was totally erased and system reinstalled by Apple repair center from scratch.

Only third party installed was Msoft Office 2016( which we use 3 machines all in all).

Cursor problem again.

Apple makes me now create partition with system without any third party. Will try but I'm sure

problem will still be there.

In images I'm adding (dating from 10 days ago), one can see clearly how text becomes jumbled, or even types in the page number box.

When problem is occurring in Finder, it makes cursor jumping from a file to another

Any idea ?
