Terrain at different altitudes near and far from the aircraft

Hey @Drake1976IT
Today I flew the DC-6 from Gibralta down along the african coast.
During the first hour auf my trip I had the same issue.

The texture tiles below my plane were different in color than the tiles farer away. Therefore new tiles, moving to my plane were popping in and tiles moving away went back to normal.

After a while this issue went away and everything was back to normal.
Thats the reason I dont have a screenshot.
I guess its just a temporary server issue.
