I am testing against the stable 3.4.y branch.
With that patch, scrolling is very slow, and it emits middle click sometimes 
while I want to scroll fast. 

Looking at the debug output, i see a lot of NOTIFY packets, for the same  
number of packets/seconds (77). So then there is 5 times less multi touch 
events. Maybe that's why.
