The thread you linked doesn't have anything to do with this, since it shows two different problems caused by other products, which were:
- a different photoreal image in one case ( the one with the airplane, it's not from our KLAS )
- a problem with elevation caused by OrbX, which you don't have.
In fact, that's how the scenery always looked like since years. I think you can see the double markings because the scenery used to have a lower resolution background, but a while ago we increased the resolution, so they are more noticeable now. We'll see if we can fix them.
