On platform GTK, revision r171957 <http://trac.webkit.org/r171957> has caused 11 new failures on this tests: Regressions: Unexpected image-only failures (11) svg/custom/textPath-change-id-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-change-id2-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-change-reference-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-change-reference-using-baseval-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-change-reference2-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-modify-child-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-path-change-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-path-change-using-svg-dom-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-path-change2-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-remove-path-pattern.svg [ ImageOnlyFailure ] svg/custom/textPath-startoffset-pattern.svg [ ImageOnlyFailure ] I have double tested this: reverting r171957 fixes this issue. You can check the diffs here: http://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r171957%20%281853%29/svg/custom/
Seems that this has also caused (at least) this two new flakiness on GTK: Unexpected flakiness: fast/canvas/canvas-strokeRect-gradient-shadow.html [ Failure Pass ] fast/css/table-border-radius-with-box-shadow.html [ ImageOnlyFailure Pass ] The diffs are: http://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r171957%20%281853%29/fast/canvas/canvas-strokeRect-gradient-shadow-pretty-diff.html http://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r171957%20%281853%29/fast/css/table-border-radius-with-box-shadow-diffs.html
Also the following test is flaky now: fast/canvas/canvas-composite-image.html [ Failure Pass ] Diff: http://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r171957%20%281859%29/fast/canvas/canvas-composite-image-pretty-diff.html
Updated the GTK TestExpectations on http://trac.webkit.org/changeset/171963 for this failures
