Usually when tap clicking on a touchpad, any pointer movements are suppressed as a tap is detected. This does not happen on my Arch machine. Whenever I tap click, the mouse pointer jumps several pixels in some direction.
How can I stop this?
(Arch is fully updated and since kernel 3.3 my touchpad is detected as "AlpsPS/2 ALPS DualPoint TouchPad".)

Could you please post the content of /etc/X11/xorg.conf.d/10-synaptics.conf ? I think your problem is related to a wrong setting.

You could try
synclient MaxTapMove=0
in a terminal. Does this help?
Offline
Unfortunately that does not help.

Does the movement occur when you click with one finger too?
Offline
I haven't clicked with more than one finger. :-)
Because the touchpad is quite unusable in this state, I haven't yet bothered configuring two finger tapping.
Edit: I hadn't noticed at first that "MaxTapMove=0" breaks tap clicking completely.

I was having the same issue. MaxTapMove on my system was set to 110. Changing it to low values might help. I changed it to 10 and I saw slight improvement.

Isn't MaxTapMove the maximum distance you can move your finger between the first and second tap when double tapping?
Consider "x" the tap locations and the distance between both "x" the maximum distance that still gives a double click:
Low MaxTapMove: x x
High MaxTapMove: x xHave you tried FingerHigh and FingerLow? Mine doesn't have these settings, unfortunately.
