The fast/shapes/shape-inside/shape-inside-subpixel-rectangle-top.html reftest introduced in r159821 is failing on the GTK port. http://trac.webkit.org/changeset/159821 http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Fshapes%2Fshape-inside%2Fshape-inside-subpixel-rectangle-top.html It also fails on the EFL port. Both GTK and EFL ports enable the subpixel layout, but the description in bug #124784 sounds like that shouldn't be a problem. Perhaps it's a matter of the saturated layout arithmetics, which both ports disable at the moment.
At least for the gtk+ port, saturated_layout_arithmetic does not solve the issue, as far as I could test.
The test fast/shapes/shape-inside/shape-inside-subpixel-rectangle-top.html is working correctly since http://trac.webkit.org/changeset/162442 I'm going to remove it from the expected failures
Shape-inside is gone for now (r166301). Closing bug.
