Today, I departed Gate E5 and headed towards Rwy 19L. As I approached the end of the runway, the ground turned from concrete color to green (as seen from the cockpit). I thought maybe my a/c lights were interfering so I turned them off and still green. I lined up on the rwy and everything was green around the a/c. Even the markings disappeared as I taxied. Once I started down the runway, everything turned back to concrete color. If I used the spot view, everything was fine. It only happened from the cockpit view and at this area.
Any idea what's causing this? I don't have any other KLAS AFCADs or scenery installed.
Thanks,
Mike Franks
