HISTORY: https://results.webkit.org/?suite=layout-tests&test=svg%2FW3C-SVG-1.1%2Fmetadata-example-01-b.svg&recent=false&version_name=iOS%2017&version_name=Ventura TEXT DIFF: I'm not going to post the SVG monstrosity here, but the important part is: -0.47 +0.470001 That text diff is from macOS arm64. iOS expects the opposite. I assume this is due to differing baselines, but I haven't checked. DIFF URL: https://build.webkit.org/results/Apple-Ventura-Release-AppleSilicon-WK1-Tests/280415@main%20(10103)/svg/W3C-SVG-1.1/metadata-example-01-b-pretty-diff.html REPRODUCIBILITY: I was able to reproduce this issue on macOS Sonoma (14.4, 23E214/arm64) ToT using the following command: run-webkit-tests -v svg/W3C-SVG-1.1/metadata-example-01-b.svg REGRESSION: Contextual information indicates this issue started appearing on macOS when we enabled UI-side compositing by default in 262629@main. I'm not sure what the iOS regression point is, as we aren't using x86_64 to run simulator tests. 2043434 1 webkit-bug-importer 2024-06-27 11:50:18 -0700 <rdar://problem/130690749> 2043435 2 ben_schwartz 2024-06-27 12:11:30 -0700 For posterity: discussed offline with Simon, who said to re-baseline to make arm64 pass and mark as failure on x86_64. 2043437 3 ben_schwartz 2024-06-27 12:21:47 -0700 Pull request: https://github.com/WebKit/WebKit/pull/30241 2043438 4 ews-feeder 2024-06-27 12:24:12 -0700 Test gardening commit 280424@main (c90807b9c23c): <https://commits.webkit.org/280424@main> Reviewed commits have been landed.
