Which state is it? I'm blind

Like also, whereabouts in the image is the pixel?

glowcap-harvest and it's in the top-left

The bug is in the call to MagickImageCollection.Optimize() here:

IconDiffBot/IconDiffBot/Core/DiffGenerator.cs

Line 299 in 7f8c211

gifCreator.Optimize();

Getting rid of it causes artifacts in the generated .gifs, though. ImageMagick issue.

Note to onlookers, the images in the linked check run are empty due to a recent server change

[Cyberboss]

Okay, so the image magic maintainers are dumb and can't decipher the issue I posted.

I assume, in order to properly report the bug, we'll be needing a C++ demonstration.
