Description

Created attachment 137257 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.
