Comment 17 for bug 633225

I've been following the xorg-devel mailing list, but I don't know how to jump in on a particular thread. I don't see the same finger movement tracking behavior that Chase described in my clickpad. Here is the way that I see it: The finger that has the greatest Y value is always reported in the non-multitouch packet. This becomes a problem if the fingers move so that the finger with the greatest Y value drops below the other finger. The 2nd finger's Y coordinate is immediately switched from the multitouch packet to the non- multitouch packet. Interestingly, the X coordinates do not follow the Y coordinates, so you end up with each fingers X and Y coordinates split between the multitouch and non-multitouch packets.
