Description Ryan Haddad 2018-09-19 10:29:07 PDT

Layout test compositing/filters/opacity-change-on-filtered-paints-into-ancestor.html is a flaky image failure on Mojave WK1.

The image diff shows that one of the blue squares is not as blurred as expected.

I have not yet confirmed, but this may have regressed with https://trac.webkit.org/changeset/235630/webkit
