The following layout tests have small pixel differences in their rendering on Win7, apparently after http://trac.webkit.org/changeset/145844 : fast/forms/basic-textareas-quirks.html fast/forms/basic-textareas.html fast/overflow/overflow-x-y.html fast/parser/open-comment-in-textarea.html fast/replaced/width100percent-textarea.html Looking at the differences it isn't 100% clear to me that the new behavior is desired; the scroll bar and top arrow look slightly worse to me. Assigning this bug to flackr to take a look. To see the differences, run webkit-patch garden-o-matic and look for these tests. I may try to suppress these failures in the meantime, so you may need to look under the "expected failures" tab for them.
The difference in the arrow is very strange. As for the track I did expect the difference but I can see that not drawing a 1px track between scroll bar buttons may be preferred. Looking into this.
