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. 696240 2 fmalita 2012-08-15 12:07:32 -0700 (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. 696268 3 achicu 2012-08-15 12:34:00 -0700 (In reply to comment #2) > (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. 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. 697489 4 achicu 2012-08-16 13:55:11 -0700 *** Bug 94169 has been marked as a duplicate of this bug. *** 703188 5 achicu 2012-08-23 11:33:52 -0700 *** This bug has been marked as a duplicate of bug 94372 ***
