From the log:

REFTEST fuzzy test (18, 294) <= (19, 295) <= (19, 294)
[...] max difference: 19, number of differing pixels: 295

Looks like we need to allow for one additional pixel to differ, i.e. broaden the pixel range to 294-295

  Now the number of differing pixels is 322.

Hi Daniel! Can you please take another look at this?

Will do! Sorry about that. I'm afk for another hour or so. Feel free to just update the pixel count in that same line that I edited, with the new value; rs=me (rubber-stamp=me) on that change, no need for formal review for this tweak I think. But I'll take care of it in a bit otherwise.
