Reading through https://bugs.launchpad.net/ubuntu/+source/xf86-input-wacom/+bug/1774242, multiple people confirmed that using the libinput driver worked for them, whereas only one person confirmed that turning off gestures worked for them--and that person was using a Dell XPS machine, which is different from the Lenovo Yoga devices against which the bug was originally reported. I suspect that bug report will get similarly re-opened with people saying that the fix didn't work for them.
