    <thetext>This is apparently expected behavior (since empty results were checked in for mac when the test was originally added in http://trac.webkit.org/changeset/109953), but I don&apos;t understand why. On Mountain Lion, there is actually a layer tree printed:

http://build.webkit.org/results/Apple%20MountainLion%20Debug%20WK2%20(Tests)/r127318%20(503)/css3/filters/composited-during-animation-layertree-pretty-diff.html

Why are we expecting empty results on Lion? Is some feature not on in Lion?

I am going to add the expected results for ML and move the empty results to mac-lion to get the bots greener.</thetext>

    <thetext>This test sometimes (rarely) produces empty results on all Mountain Lion bots (WK1 and WK2).

Also, I can reproduce getting empty results every time when it&apos;s run repeatedly:

$ run-webkit-tests css3/filters/composited-during-animation-layertree.html --repeat-each 100
…
[2/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)
[3/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)
[4/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)

[6/100] css3/filters/composited-during-animation-layertree.html failed unexpectedly (text diff)
…

Marked as flaky in &lt;http://trac.webkit.org/r157625&gt;.</thetext>

    <thetext>GLIB ports (WebKitGTK and WPE) produce similar results (https://bugs.webkit.org/show_bug.cgi?id=171600).

The general baseline is empty. Isn&apos;t that a mistake?
