Public bug reported:

Not sure if this is the correct package to file this under, so please
move it if needs be.

I have a Wacom Intuos Pro 4, which has touch capability. Single finger
taps, two finger scrolling and other multi-finger gestures all work
fine, but two finger taps only register about one in ten times.

If I run evtest I can see the tap being picked up by the tablet (I
think), but it doesn't register as a two fingered tap by the system.

Here is the result of running evtest and tapping with two fingers, thsi
does not get interpreted as a two-finger tap:

 evtest /dev/input/by-path/pci-0000:00:14.0-usb-0:14:1.2-event-mouse
