I think the worst examples of it during flight are when looking around while flying something with a lot of wires (biplanes for instance.) In most modern aircraft it isn’t too distracting. When flying anything with a lot of doodads sticking off of it, I tend to avoid clouds. Worth noting too it seems to mainly happen with dark clouds, not really noticeable otherwise (likely because of how bright the ghosting itself is though.) Granted, I try to avoid most clouds anyway since that’s what I’d do IRL.
