Description: transforms/2d/scale-change-composited.html transforms/2d/rotate-change-composited.html transforms/2d/translate-change-composited.html I went back further and can see build https://ews-build.webkit.org/#/builders/10/builds/38853 appears to be the first occurrence. Around that same time period commit r268444 was made. This is were the test were added. The commit has to do with transform-origin is applied on top of invidivual CSS transform properties on composited layers, which could have introduced the flakiness. The change was introduced here https://trac.webkit.org/changeset/268444/webkit.
