I noticed that too. But  I find it's more randomly. Noticeable where I have small features like the small farm. I come back form a neighbour and suddenly the roof is obscured by uncleared dark trees. then later, the roof is clear again....Some quirk in the server. Same as the islands sometimes briefly disappear and everything seems to be floating on water. Or when not all the dragons and/or habitats show.
