--- Comment #11 from Peter Hutterer <peter.hutterer at who-t.net> ---
ok, after playing around with this on my touchpad here and looking at your
recording, the issue seems to be that when putting the fingers down we get a
massive cursor jump, sometimes across half the touchpad (also likely the source
of the error message). This jump triggers the direction detection, making it
look like a pinch. Fixing this requires quite a few hacks, so first I need to
know if this is still an issue with the RMI4 support. Please test dmitry's
kernel here:
http://lkml.iu.edu/hypermail/linux/kernel/1612.2/00646.html

Note that's an early v4.10 kernel, some stability issues are expected. Once
installed, the touchpad will come up with some weird-looking name (SYN002 or
similar) that's how you know it's using the RMI4 protocol.
