    <thetext>Layout test compositing/visibility/visibility-simple-video-layer.html has been frequently timing out or failing since r214240. That&apos;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.</thetext>
