commit 35057f5a449890874b32f302b5bde53aa5b04fa0 parent 6350ba1768626c9da3e55dfdcf3a7ea6f9e9c6b1 Author: Sam Fortiner <samfort@microsoft.com> Date: Wed, 7 Jan 2026 09:48:07 +0000 Bug 2008796 [wpt PR 57019] - Enable scalefactor200 effect-reference-feimage tests, a=testonly Automatic update from web-platform-tests Enable scalefactor200 effect-reference-feimage tests The expected vs actual results in this look identical to the eye and appear to be slight anti-aliasing differences at color boundaries. Detailed analysis: There are three unique and identical clusters of images. Cluster A - the expected rendering which is identical across platforms. Cluster B - the actual renderings without will-change Cluster C - the actual renderings with will-change Cluster B <-> C: Differ by 21 pixels with a max per-channel delta of 1. Cluster A <-> B and A <-> C: Differ by 0.9% of pixels with a max per-channel delta of 11. This CL modifies the image comparison to allow fuzzy matching with these values.
