The fuzzy match metrics added with that commit seem to have made it pass on arm64 based macOS queues, but it continued to fail on x86 macOS bots as well as both arm64 and x86 iOS simulator queues. The fuzzy match change in https://commits.webkit.org/262037@main may have been too extreme and might cover up real failures. 1943542 6 bfulgham 2023-03-23 15:59:12 -0700 (In reply to Ryan Haddad from comment #5) > It looks like this test was re-enabled with > https://commits.webkit.org/261903@main. > > The fuzzy match metrics added with that commit seem to have made it pass on > arm64 based macOS queues, but it continued to fail on x86 macOS bots as well > as both arm64 and x86 iOS simulator queues. > > The fuzzy match change in https://commits.webkit.org/262037@main may have > been too extreme and might cover up real failures. I think the wider fuzzy-match values are better than the original state of an expected image failure. It's frustrating that Arm and Intel have different pixel rounding on these images.
