Imagine you see some picture that should not appear in normal circumstances, e.g. seemingly when graphics card or some program malfunctioned and display nonsense.
For example, overheated graphics card crashed and the system frozen, displaying severely corrupted image (it may look unrelated to what it should display, but also may be related).
What license is such picture of? Can it be included and used somewhere? Should it be similar to just photographing nature? Does it matter what was running before the crash (e.g. proprietary game with proprietary artwork that can sneak into resulting image)?
