This is when piloting skills come in. If you keep some movement in either direction or flying ATTI mode you should not have the left right jitters. The GPS is constantly trying to correct the heading when sitting in place.
But the GPS doesn't correct position with Yaw, it is correcting position on the horizontal plane. In other words, it doesn't yaw to move sideways. It tilts horizontally to move sideways.
As noted, the flight control system does control yaw, though technically it's
not the GPS part, but the compass part. As noted, GPS is used to maintain position, but the IMU is used to maintain attitude and the compass is used to maintain heading. In gusty conditions, the wind will induce yaw as well as movement in every other dimension; the flight control system will have to work in the yaw axis to maintain heading, and the accuracy of the compass and the gain of the control system will limit how steady it can be.
Having said that, the controls out of the box are very twitchy for my (relative noob) tastes. I'd love to be able to control the linearity of the controls, so that modest stick deflections make small changes, but as you get nearer to the stops the control becomes more aggressive. That way you still have the full range of control if you need it, but it would be easier to do fine adjustments.
