I'm testing the new clickpad support from ppa:chasedouglas/clickpad on a MacBook Air 4,1 with a bcm5974 touchpad. When I have the touchpad pressed down with one finger in the "right button area" of the touchpad, placing a second finger on the touchpad causes the mouse pointer to jump. The direction and distance of the jump is related to where I'm placing the finger on the touchpad -- higher on the touchpad might cause it to jump up, lower on the touchpad might cause it to jump down, etc.
Note that this doesn't happen every time I place a second finger on the touchpad. I can't quite determine the pattern, but it seems to depend somewhat on where each finger is located on the touchpad. Sometimes I can't get it to happen at all.
