fast/scrolling/mac/overflow-scrollbars-toggle-dark-mode.html is a flaky image failure on macOS wk 2. The failure mostly occurs on BigSur running on Apple Silicon Macs. However, it has also failed twice on Intel Macs running Catalina. HISTORY: https://results.webkit.org/?suite=layout-tests&test=fast%2Fscrolling%2Fmac%2Foverflow-scrollbars-toggle-dark-mode.html IMAGE DIFF URL: https://build.webkit.org/results/Apple-BigSur-Release-AppleSilicon-WK2-Tests/r277080%20(1316)/fast/scrolling/mac/overflow-scrollbars-toggle-dark-mode-diffs.html I have attached the images to this bug below.

I don't have access to an Apple Silicon Mac, so I can't reproduce in that environment. 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.
