The following layout test is flaky (crashes sometimes) on platform GTK fast/regions/repaint/region-painting-composited-element.html
The test fast/regions/repaint/region-painting-in-composited-view.html shows the same behavior (crashes sometimes)
Also the test fast/regions/repaint/region-painting-invalidation.html crashes sometimes. The issue don't seems easy to reproduce. I have been running the tests in a loop and i was unable to cause the crash. However they crash on the bots from time to time so I'm marking this 3 tests as flaky on the test expectations.
Created attachment 235994 [details] Crash for fast/regions/repaint/region-painting-in-composited-view.html Finally I was able to reproduce the crash on one of them by running all the 3 tests in a loop until one crashed. I'm attaching the GDB backtrace for the crash for fast/regions/repaint/region-painting-in-composited-view.html
I have added this test to the list of expected failures for GTK on https://trac.webkit.org/r172017. Please remove it from the list if you fix the issue. Thanks
