Comment 14 for bug 754948

This bug also affects all compiz edge bindings with mouse button presses in it on dual monitors with nvidia driver 270.41.06 under both gnome and unity, and for some reason the bug doesn't exist if you're in expo or shift switcher or scale. For example if you have a binding for magnifier set for a screen edge with a mouse scroll, it will not work on the normal desktop but it'll work if you switch to expo or shift switcher or scale with a little glitchy screen tearing.
