Three finger gestures don't work and inconsistent three finger tap behavior
Summary
On HP Spectre Late 2017 model, I cannot make three-finger gestures like pinch to bring up the overview menu work. Four finger gestures for switching workspaces seem to work perfectly. Also, the behavior of the three-finger tap is inconsistent. Sometimes it behaves like a middle button click, while other times it stops responding to three-finger taps.
Steps to reproduce
Three-finger pinch to zoom out should bring up the Gnome overview menu. Instead, it does not respond to that gesture or any other variations of three-finger gestures. Tapping three-fingers emulate a middle-click of a mouse at sometimes (most notably after a fresh reboot), and other times it fails to register.
