Hello Marty,
i'd included 3 screenshots in the question, but maybe they're impossible to read?
normally, when the sun rises, you start to see something at the horizon, and slowly it's starting to get light. when i'm flying,i start to see the light not from the horizon, but from the center of the earth. slowly, the light is raising, and at a certain time, it pops out above the horizon. but this is very unnatural and well... weird...
you should be able to see that in the screenshots, if not, i can include them again, if you want?
the bug report, i haven't filed yet, because i don't really know wether it's a bug, so i was a bit hesitant to do so...
hope this clears things up...
grtz,
Serge Morabito
