The clutter is popping because of thicker Alpha/transparency texture in LODs. otherwise the grass would get extremely thin/transparent in the distance and you would see soldiers and other models through it. The pop is much more noticeable on your video, because there is very big contrast between ground texture, satelite map and the clutter. Try to reduce the contrast and the "pop" will be much less noticeable. As on Livonia.

this is the difference between normal and high brightness...expected difference

same here
