This bug existed since SU5 in august.
the highest resolution LOD loads not only a hi-res texture but a completely different one. you’ll see this effect at a couple of different locations all over the world actually. since it only shows when flying lower then 1300ft most users flying IFR Airliners won’t even notice it, the VFR GA users do though.
Well besides that, so many different post were made about this, some were closed, most ignored, especially by asobo.
