Comment 3 for bug 147230

Compiz does not seem to be respecting the initiate condition for viewport switching with a touchpad. It it supposed to be button2 (middle?) by default. I don't know what this means for the touchpad, but if I add the Control key modifier I still see the viewport switching occurring without pressing it. This compounds the problem of ridiculous sensitivity - I can accidentally scroll viewports by dragging horizontally across the middle of the touchpad if I catch enough of the edge where vertical scroll takes place and (presumably) also move very slightly up or down. As you can imagine, this occurs quite often when moving the mouse around the desktop. I think it's very surprising and confusing for new users, and no less annoying for more experienced ones.
