I'm trying to come up with a cross-device code that handles pointer events. I'm running this code successfully on Chrome/Android (using USB debugging), but the Chrome desktop just acts up and keeps firing pointermove after the mouse has been released.

(Another problem is that the moves are not as smooth as on the mobile)

Playable demo
