I think a lot of the problem is that the downward VPS doesn't have enough contrast on the ground to help it stay stable. The GPS helps, but I believe below a certain height the Mavic will start giving priority to the VPS for positioning relative to the ground. This is, perhaps, also related to the lack of a dedicated ATTI mode like on the P4 etc.
I am wholly speculating, based on very little real evidence beyond what I have read here in the past.
Hmmm, I think you are right.
But I'm afraid of turning off the VPS in forest, because there are trees they suddenly jump out and try to crash my Mavic ![](//forum44.djicdn.com/static/image/smiley/emoji/28_2x.gif)
ATTI Mode would be a great solution, but I think this would never come to Mavic. DJI Ken wrote about this a few weeks ago.
