On platform GTK, revision r171957 <http://trac.webkit.org/r171957> has caused 11 new failures on this tests:

I have double tested this: reverting r171957 fixes this issue.

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:

Also the following test is flaky now:

fast/canvas/canvas-composite-image.html [ Failure Pass ]
