Description: compositing/debug-borders-dynamic.html The first image failure that I see this on the dashboard was 09/29/20 at r267758, but does not appear to be relevant to what would have caused this. There is only one day of test history with this being the only image failure on the dashboard so far. The test was expecting to repaint 2px solid red border with transform, but seems to have returned without transform. History: https://results.webkit.org/?suite=layout-tests&test=compositing%2Fdebug-borders-dynamic.html&limit=50000&version_name=iOS%2014 Diff: https://build.webkit.org/results/Apple-iOS-14-Simulator-Release-WK2-Tests/r267758%20(20)/compositing/debug-borders-dynamic-diffs.html

I have marked this test as image failure while this issue is investigated. https://trac.webkit.org/changeset/267776/webkit
REPRODUCTION STEPS Build 17H35: I can reproduce this image failure with most recent available spade r267194. Build 18A393: I can reproduce this image failure on all spades tried between r262500 and ToT 267802. The test will usually fail within the first 50 to 100 iterations. Because the test was consistent in failures, I cannot pinpoint a change that could have caused this.

compositing/debug-borders-dynamic.html Is still a flaky failure on iOS Debug queue, as an expectation has not been set.
This should be solved with pixel tolerance (it's some pixel fuzz around the repaint counter).
