Public bug reported: In the "Mouse and Touchpad" application, "Disable touchpad while typing" is ticked - however, this seems to have no effect. Catching the trackpad whilst typing sends the cursor ricocheting across the screen.
Expected behaviour: "Disable touchpad while typing" does indeed disable the touchpad within {x} seconds of a key-press occurring - or, if this functionality isn't available with this hardware, the option should be greyed-out/disabled. Actual behaviour: The "Disable touchpad while typing" check-box seems to have no effect on the system - there is no noticeable change of behaviour no matter what the state of the control.
