There is a minor problem where when you extend the speed brakes and turn the yoke slightly to, say, the left, the spoilers on the right side retract all the way down, not halfway down or anything in between, it's either fully up or fully down when you turn the yoke. It's hard to find a video of this, but you can just see it at about 1:07 when the aileron moves and the spoiler slightly retracts, whereas on the PMDG 777, the spoiler would go all the way down.
