I don’t know what happened with the latest updates, but somewhere around 6.4.x the touchpad multi finger support got very flakey. 3 or 4 finger side to side swipe to move to another virtual desktop works fine. But 4 finger swipe up/down just stops working after 5-10 minutes of being logged in. Honestly, it all worked fine back in the 5.x.x days, then when 6.x.x happened it started happening infrequently. But now, it makes that 4 finger gesture pretty useless.
Not meaning to complain too much, but as I understand, not much I can do to fix this?
