I think it's the Bijan season texture mod... possibly the part of it that changes scenery tiles to fall colors or something.
That's it! I just bought that mod recently and had not tested it with the aircraft models featuring the proline style moving maps. Thanks guys, I thought myself or recent updates had screwed something up. No biggie, when we get back to spring time, I will likely remove that folder.
). Remove it and use only trres + models, or use it with non G1000 models or you can live with this ; ). Maybe REX will do something for this in his addon (they promised ground shaders too). Its a known problem.
