&gt; &gt; &gt; You are assuming again that there's a single issue.
&gt; &gt; 
&gt; &gt; No, clearly there were many different issues, as you've fixed three
&gt; &gt; different issues so far....
&gt; &gt; 
&gt; &gt; &gt; I think the situation now
&gt; &gt; &gt; is mostly the same to what we had before switching to the threaded
&gt; &gt; &gt; compositor.
&gt; &gt; 
&gt; &gt; Yes, except for the fact that sometimes a bunch of tests pass when they
&gt; &gt; usually fail. In build #18023 we have 84 unexpected passes; that never
&gt; &gt; happened before. What's interesting is these tests either always pass or
&gt; &gt; always fail in a particular run of run-webkit-tests; they are clearly flaky,
&gt; &gt; but they don't contribute to the flakiness count.
&gt; 
&gt; We should probably mark them as pass, to see what's wrong when they fail</span >

That don't makes much sense to me.

You can see the failure diff even if they are expected failures. You just have to navigate under <a href="https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/">https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/</a> to find them.

For example: 

1) Check the unexpected passes at end of build #18023 <a href="https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Tests%29/builds/18023/steps/layout-test/logs/stdio">https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Tests%29/builds/18023/steps/layout-test/logs/stdio</a> and pick 1

2) I pick: imported/mozilla/svg/blend-difference-stacking.html

3) Check that on the next build that test failed. Log of the next build: <a href="https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Tests%29/builds/18024/steps/layout-test/logs/stdio">https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Tests%29/builds/18024/steps/layout-test/logs/stdio</a> &lt;--- yes it failed

4) Go to <a href="https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/">https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/</a> and find the results for build #18204 -&gt; <a href="https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r205335%20%2818024%29/">https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r205335%20%2818024%29/</a>

5) Now under that folder navigate to imported/mozilla/svg/ and look for the blend-difference-stacking diff

6) Here you have it: <a href="https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r205335%20%2818024%29/imported/mozilla/svg/blend-difference-stacking-diffs.html">https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r205335%20%2818024%29/imported/mozilla/svg/blend-difference-stacking-diffs.html</a></pre>
