I've been having this weird issue with some pictures and video of mine, and haven't been able to find ANYTHING online about it.
It might take some good eyesight, but if you can see it like me, the green building in the upper-center of the picture has this circular pattern that almost looks like a fingerprint. However, when you zoom in on the picture, it goes away, revealing only the natural horizontal lines of the roof.
This seems to be an optical illusion that appears very often when I shoot near brick buildings or roofs with lots of lines. I don't imagine that the camera itself is faulty, but I never see anything like that in other people's photography. What's going on here, and is there anything I can do to remove it (either in camera settings, or editing afterwards)?
