This issue is a new copy of this issue : https://bugs.chromium.org/p/chromium/issues/detail?id=466564

This issue happens on webkit based browsers on multiple 3M touch devices.
Kernel has been upgraded, Touch controller firmware too, and the issue remains.

Some specific controllers produce this issue : 
Bus 001 Device 004: ID 0596:0530 MicroTouch Systems, Inc. (on a 3M C4667PW)
Bus 001 Device 004: ID 0596:0517 MicroTouch Systems, Inc. (on a 3M M2467PW)

And this controller from 3M is working fine 
Bus 001 Device 004: ID 0596:0521 MicroTouch Systems, Inc. (on another 3M M2467PW)

Some investigations has been done with 3M technical team, and since it's happening only on webkit based browsers (chromium, google-chrome, electron, atom-shell tested), and not on native ubuntu interfaces, nor firefox, it seems to be a webkit/chromium issue.
