    <thetext>It looks like enabling accelerated drawing at 256180@main caused the following 15 tests to have constant ImageOnly Failures:

    <thetext>The ImageDiff for all of these tests appear to only be off by .01%. Still, I was able to reproduce them all at Ventura Debug ToT running the test as follows:


run-webkit-tests &lt;insert test name here&gt;

I also was able to determine that the regression point where these failures were introduced is 256180@main. The failures did not reproduce at 256179@main</thetext>

    <thetext>(In reply to Robert Jenner from comment #6)
&gt; Re-opening for pull request https://github.com/WebKit/WebKit/pull/6877

There was an additional fix needed for:

compositing/geometry/css-clip-oversize.html
fast/borders/border-painting-inset.html
fast/borders/border-painting-outset.html
fast/layers/parent-clipping-overflow-is-overwritten-by-child-clipping.html

So I have submitted a PR for them above.</thetext>
