The question seems to attract low-effort answers, which point to sites that I originally used when researching the subject. I've also reviewed the linked source code multiple times against the answers and the outcome has been the same: the artefacts remain.
My feeling is that the question fails to pin-point the problem concisely and therefore distracts people who might be able to answer. How can I improve the question so that it would eventually get answered and my problem would be solved?
