--- Comment #2 from vive.li...@belgacom.net ---
I have had the same problem since I started using wayland (with kde plasma) in
may 2022 but I have the feeling that it got worse recently : previously it only
happened a few times a day, now it is every few minutes. I am now using plasma
6 but I wouldn't say for sure that it got worse since plasma 6. Maybe it is
just me that does whatever triggers the problem more often.
Contrary to what OP suggests, I'm not sure the problem is triggered by using 4
finger swipe (if it is, it is not every time). As far as I am concerned three
finger tap (emulating middle click) or three finger swipe stops working
randomly and I usually get it back working using a 4 finger swipe.
I do not think this is a general driver bug because it never happens with
hyprland that I sometimes use on the same machine with the same OS (arch
linux). It makes me think it is specific to kde plasma. Not sure.
My laptop is a Lenovo E595 and this is what I can find in journalctl just after
the problem is triggered :
