Bug 96416 – Layout Test compositing/overflow/overflow-scaled-descendant-overlapping.html is failing after r127789

• Status: NEW
• Component: Tools / Tests

The following layout test is failing on chromium-mac since http://trac.webkit.org/changeset/127789:

compositing/overflow/overflow-scaled-descendant-overlapping.html

fsamuel added two rebaselines, in http://trac.webkit.org/changeset/127898 and http://trac.webkit.org/changeset/128069, but they both look wrong to me (they add a horizontal line down below the box that's not present on other platforms). I'm inclined to mark this test as failing on mac, remove the bad baselines, and hand it off to twiz. There's no way to get the tests passing without an expectations update anyway, since r128069 added a baseline that differs between release and debug on 10.6.

@flackr i know your scrollbar change also affected this test, so maybe they are related.

I spoke to the original author before i rebaselined. The issue is a compositor issue unrelated to the test. Functionally speaking, the test is outputting the correct result.
