I just wanted to chime in that I also have the floating buildings problem at Bembridge. I also get it in a couple of other places on the IoW but the worst area is Bembridge.
Also while on the subject of Bembridge the airport itself doesn't line up properly with the photo textures in True Earth Great Britain South, its as if the whole airport is a few feet to the west of the textures.
