seen any jumpiness. But, based on the data I am seeing that if I
lift my finger and place it again in a short period of time the
first event or so will be at the location of the previous
contact. Then it will switch over to the current location. When
switching over to hid-multitouch I was unable to reproduce this
behavior. This definitely could be the source of the jumps.
to test any patch you think would improve the situation. Moving one finger
slowly in a figure-8 across my touchpad shows the issue clearly for me. The
small variations in speed of my finger due to the friction on the trackpad
get magnified to relatively large jumpy pointer movements on screen. It
seems much more noticeable in diagonal movements than completely vertical
or horizontal movements.
evemu-record of some movements or something like that? Or do we need to
bring Peter into the loop in case it has something to do with libinput?
