Itís not common in photographs, but is very common in scaling various patterns and other kinds of synthesized images. As I wrote in my original post, even before I saw the link I included, I had come across the issue many times. However, I never posted about it anywhere, as it didn't even cross my mind it could be fixed, I just assumed that's just how image scaling works. Perhaps that might explain why there were so few results in your search.
