Default [Q] GMD Gesture not good working on XT1033

Before I got my Moto G(Dual-sim Edition),I have always play my nexus 4 with GMD Gesture,so that I have a very good experience when full screen use,but the GMD Gesture doesn't work so well on Moto G,especially multi-touch it never work normally.
Does anyone know the reason or the solution about that?
