I just build from Linus' tree from Saturday (ef82f1ad), and touchpad

I'm not moving at all or I'm trying to teleport to the edge of the
screen.

Is this a known problem or should I try to track it down?

Did this work properly in 4.11?

Is this G11 based chipset? (IOW, is this device driven by wacom driver?). 
If so, 6f107fab8 and/or 60a2218698 might be potential candidates.
