The scenery is permanently installed.  I do not run TerraSync.

As stated in the original report, this occurred on two successive flights in two days.

Another responder suggested it was a problem with the 2D cloud cover layer and that seems to make sense, because as I said, the plane never seems to get closer to the "tile" edges.  Since reading the e-mail, I haven't had a chance to test that theory by turning off METAR immediately when seeing the effect, but I will do so when I get the chance and report back.
