In the image, from top to bottom: - the output of the first down-scale pass where the size of the output was exactly the size of the input - the output of the second down-scale pass where the size requirement wasn't met - vertical blur - horizontal blur We can see that some glyphs got darker than others at the second down-scale pass and stayed darker after the blur although blurring makes it a bit less noticeable. The original test case has a lot of text shadows stack on top of one another which amplifies the error.
