However, I was able to reproduce the failure on an Intel Mac running Catalina Debug ToT using the following test: run-webkit-tests fast/scrolling/mac/overflow-scrollbars-toggle-dark-mode.html --iterations 1000 -f I was also able to reproduce the failure over 5,600 revisions back. So this appears to have been a flaky failure for a while. 1757756 3 jenner 2021-05-06 17:57:42 -0700 Updated test expectations here to flaky ( Pass ImageOnlyFailure ) here:
