The following layout test is flaky on all platforms compositing/geometry/limit-layer-bounds-opacity-transition.html Probable cause: This test became flakey recently. I was able to reproduce the failure using run-webkit-tests --root testbuild-236502 compositing/geometry/limit-layer-bounds-opacity-transition.html --iterations 500 -f I ran this on Mojave. This gave me a range of possible revisions for the regression between 236497-236502. Looking at the revisions I think either 236500 or 236501 are at fault but I am not sure.
