Don’t know if you’re talking about the same issue, but mine is a seroius elevation issue that stretches from the beginning of runway 29 to the middle of runway 34, taxiways included, in the default airport (no gaya or freeware add ons). The problem disappears if i switch off the photogrammetry.
Is that the same of yours? And if so, how come it’s still there after 18 months?!
