I was able to reproduce at iOS 17 Release ToT running the test as follows: run-webkit-tests --iOS-simulator <test_goes_here> When I reproduced this was the output: [1/5] http/tests/css/css-masking/mask-external-svg-fragment.html failed unexpectedly (reference mismatch maxDifference=5; totalPixels=8248) [2/5] http/tests/css/css-masking/mask-external-svg-image.html failed unexpectedly (reference mismatch maxDifference=5; totalPixels=8248) [3/5] http/tests/css/css-masking/mask-external-svg-mask.html failed unexpectedly (reference mismatch maxDifference=5; totalPixels=8248) [4/5] http/tests/css/css-masking/mask-inline-svg-image.html failed unexpectedly (reference mismatch maxDifference=5; totalPixels=8248) [5/5] http/tests/css/css-masking/mask-inline-svg-mask.html failed unexpectedly (reference mismatch maxDifference=5; totalPixels=8248)
