Symptoms

Stylus taps are registered as well as button presses (on the last cursor position). Cursor doesn't change position."Test tablet" in "Drwaing Tablet" KDE settings only displays Stylus release events.X11 works.Finger touch still works.

Solution

Rename or delete ~/.config/kcminputrc, or remove config section related to "Pen" (not tested). Deleting the config resets other mouse pointer settings like speed, device enabled/disabled and calibrations.Then log out and log back in.
