Do you have the same issue if you follow the OP’s steps to reproduce it?
Didn’t notice until second flight at the world map, saw this oddity. (See screenshot)
Provide extra information to complete the original description of the issue:
Loaded up a flight at KDEN, used FSLTL, looked fine. Loaded up at KLAX, used FSLTL, looked fine. Loaded up at KSNA, used FSLTL, looked fine. Went to world map in the dark area and took screenshots.
If relevant, provide additional screenshots/video:
First time I’ve seen this happen…I’m not sure if it’s an issue worth cleaning out my community folder yet…Maybe it’s been there awhile…no idea. I just happened to zoom way out and noticed it…lol. I’m doing another few flights today…I’ll check each time to see if my new guest keeps reappearing again…haha.
I have seen the same bug (on DX12, AMD 7900XT)… and I find the argument that it is “not a bug, because of add-ons” somewhat … confusing.
It is so obviously a bug of the MSFS software (stack) and it looks pretty severe to me, because there clearly is some kind of “memory management GPU state cleanup” problem.
