It's been years since I've seen this mess, but it's happening more often lately. I tried changing AntiAliasing settings and deleting the shaders. . .each one separately seemed to fix it but it came right back the next time I loaded the Sim. I also tried "verifying" the Orbx scenery I have installed to no avail.
I've not done any tweaking of FSX in years, and the graphics card gets periodic driver updates as they're available but this oddity seems unaffected by the updates.
Anyone have a suggestion as to what it might be?
