Cursor randomly jumps and cannot be controlled.
It works normally sometimes, until it decides to jump randomly and I can't control it anymore, closing the lid and opening it again helps most of the time, but only for a little while. The laptop is unusable because of this.
Up to date Debian 9 with GNOME on Acer E11 ES1-111M-C9LS.
The whole touchpad is clickable. I tap to click. Its physical size is 105x60mm

libinput-debug-events (bug is present for a few dozens of seconds at the end, but not till the end because I closed the lid and reopened it, I couldn't CTRL+C otherwise): libinput-debug-events
