Created attachment 137257 [details] A series of two-finger movements, the last of which is recognised as a POINTER_MOTION When touch-size-based palm rejection is triggered, two-finger scrolling is occasionally mistaken as one-finger movement, or cursor movement. This problem doesn't seem to happen when the palm isn't there. In the recording, the last two-finger movement is mistaken as one-finger movement. As in bug103809, I have trouble replaying the record on my non-MacBook machine, so I'm not sure if this is of much help.
urgh, I lost the hwdb again that I need for this device. what are your palm detection thresholds etc? Can you paste your hwdb file here please, thanks
Sorry for the very late response, I've been too busy to fiddle with the touchpad lately. I'm not sure what you want here.

Created attachment 138658 [details] A series of two-finger scrolling movements, some of which recognised as pointer motion Also, I've discovered that the problem also occurs when there's no palm.
Replaying with libinput 69fe467fbacbc8376d548c3 I can only see pointer axis events, no motion events, sorry. I can't debug this if I can't reproduce it here.
