Yes, firmware is up-to-date (/etc/update-motd.d/85-fwupd signals when new versions are available). > it may be libinput as the device driver.

Sometimes clicks are ignored > when a finger is at the bottom touchpad edge. When I tried, I tested clicks on various parts of the touchpad. But I would say that even if clicks are to be ignored, an event is normally generated by the kernel. I could see that the kernel generates a BTN_LEFT event even when it doesn't know where the click has been done; in such a case, I get no clicks at the X11 level (obviously).
