These tests are somewhat frequently reported as "image failure". http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=svg%2Fanimations%2FanimateMotion-additive-2a.svg http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=svg%2Fanimations%2FanimateMotion-additive-2b.svg I can't actually see the difference, even on a difference image, and even when re-computing a difference it in a graphic editor. Weird.

> even when re-computing a difference it in a graphic editor Another editor shows a very small color difference. I wonder if this has anything to do with how alpha is applied.
Marked as flaky in r180462.
Looks like we are seeing the same behavior with: svg/animations/animateMotion-additive-2c.svg svg/animations/animateMotion-additive-2d.svg created new bug https://bugs.webkit.org/show_bug.cgi?id=187345 to mark tests as flakey
I reproduced the flakiness locally for all four tests. I ran the test for 500 iterations each, and they all fail roughly 1/5th of the time.
