I have finally installed Prepar3D 1.4 and the first thing i noticed is when Viewing an ai aircraft from a specific angle (any angle, depends on the aircaft) the blue sky turns to a black sky as soon as I moved around the aircraft the sky changed back this seems to mostly happen when viewing aircraft parked on the ground but i have seen this happen to aircraft in the sky

all i did to find this was open up flight anywhere and view any ai plane from the drop-down menu and by using the spacebar and scrolling around the aircraft the sky would change black suddenly, I scrolled around the aircraft more to find the exact point when the sky changed black

P3D did not freeze or jump or anything when this happens

Im running quite a powerful system with an Intel i7 and a GTX580 with P3D installed on a seperate drive on its own

I had no addons installed when i saw this
