I've had this issue for sometime, would be great if it could be figured out.
At KCLT, I'm noticing floating textures that appear as groups of white lines on the runways. These textures will 'glide' down the runway on approach or landing, over the ground ground textures. I'm thinking this is related to some elevation issue - possibly from Orbx? I've used the vector elevation tool to try to fix, but I think it ended up causing more issues in other airports (I'm not experiencing odd elevation and floating textures at other devs airports that I've never had issues in the past, just since I've run the Orbx aec tool).
I've tried to move the stacking order in the library, but this doesn't help.
Appreciate a fix, thanks
