The svg/as-background-image/svg-transformed-background.html reftest was introduced in r143541. http://trac.webkit.org/changeset/143541 The failure on GTK and EFL is minimal, I'll attach the image diff. http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=svg%2Fas-background-image%2Fsvg-transformed-background.html The same test is failing on the Qt port due to non-sharped circles, covered by bug #110442.
