Yep, this is a side-effect of using the "real" multitouch protocol. This
is a class of device that is called semi-mt (semi-multitouch) in the
vernacular of the multitouch protocol, because it only provides limited,
somewhat unreliable information about multiple touches. For these
devices only basic, two-finger gestures are supported. We should be able
to special-case the xorg drivers to allow three-finger click and drag
for the elantech hardware because there's enough information to support
these, but that would be a follow-up to getting the new protocol support
into the driver.
Thanks for testing!
