svg/W3C-SVG-1.1/metadata-example-01-b.svg
This test is constantly failing on macOS arm64, and iOS simulator running on x86_64 machines.
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.

For posterity: discussed offline with Simon, who said to re-baseline to make arm64 pass and mark as failure on x86_64.

There's another test exhibiting similar behavior. I'm going to do the same for that test.
Test is: svg/custom/use-on-symbol-inside-pattern.svg

And another: imported/w3c/web-platform-tests/svg/import/metadata-example-01-t-manual.svg

The first re-base effort did not fully resolve issue. With the above commit, should resolve other issues.
