Two-finger swipe-up/down gestures behave abnormally after update

When I swipe up (down) with two fingers while the cursor is on the desktop background (i.e. not on top of an app window), Manjaro switches the virtual desktop to the left (right). Two-finger swipe up / down on top of an app window does what it should, namely scroll up or down when there is a scroll bar, if there is no scroll bar then it does nothing. It looks like after the last update, certain gestures were defined that would switch virtual desktop without my knowledge. I want to disable these gestures.
