Scenery Question - unusual visual

[Duckie]

Doing some tweaking on an airfield I did a while back and ran across this. Note - this was not happening on old Windows 7 machine.

I converted a B206 to scenery library and I get this unusual visual now on my new system. Below are two screen pairs of screen shots. One on the ground and one in the air. Each pair is the exact same shot but at a different viewing scale. One shot the textures show up just fine but change magnification just a bit in the same shot and the textures go to black.

I made no changes to the textures and when I converted I used MCX and converted and then exported to .bgl.

Any thoughts on how to correct this if possible?

Thanks Steve

From the air, same shot on pause different magnification
