I have another post here Support Initial Layer not adhering to bed , though this seems more like a bug so I am posting it here.
Update: I’ve recreated this same behavior in the 2.7.x release from this morning.
The first main support printed seems to have the proper initial layer density, however all other supports print an initial layer that is more like 50-60% density.
Another example is posted below. Both supports are from the same print, the one with a solid initial layer (right) was the first support printed, and the one that is more like 50-60% (left) is the one that was printed second.
