Description Michael Catanzaro 2017-05-08 20:52:49 PDT
Layout test compositing/visibility/visibility-simple-video-layer.html has been frequently timing out or failing since r214240. That's surely an unrelated commit, but we the commit that introduced the problem is probably not much older than that.

Expected: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r216473%20(979)/retries/compositing/visibility/visibility-simple-video-layer-expected.png
Actual: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r216473%20(979)/retries/compositing/visibility/visibility-simple-video-layer-actual.png

Updating expectations accordingly.
