The bug is introduced by http://trac.webkit.org/changeset/125462 . The issue is that copyUnmultipliedImage and copyPremultipliedImage don't do the color conversion on Mac. There are other filters that are also affected, for example FEComponentTransfer, FEGaussianBlur, FEComposite, FELighting, FEConvolveMatrix. -webkit-filter: blur(0) has the same issue.

(In reply to comment #1) > The bug is introduced by http://trac.webkit.org/changeset/125462 . Are you sure that the new results are incorrect? After 125462 filters are applied in a different color space (linearRGB, per spec), so the images are expected to be different. The intent was to mark them all for rebaseline, but some were missed.

After 125462 filters are applied in a different color space (linearRGB, per spec), so the images are expected to be different. The intent was to mark them all for rebaseline, but some were missed. I think -webkit-filter: blur(0); should not change the colors at all. Also, adding a grayscale(0) before the blur(0) fixes the issue, that's why I think that is an implementation issue.
