See, for example, http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r119184%20(24339)/results.html However, when I run locally I don't see these failures at all. Not really sure what the best thing to do to get the bots green would be. Here is an example of the output of one of the failures that is very typical: ---

<rdar://problem/11572371>
Interestingly, it looks like when I run locally I don't automatically run the compositing tests. When I run locally by explicitly running a subdirectory of the compositing tests, I see these failures. I am going to start landing expected (failing?) results to get the bots greener.
I also think that the tests are affecting each other in some way, because when I run compositing/iframes by itself locally, I only get one failure. However, if I run compositing/geometry compositing/iframes, I see all the failures the bots are seeing.
Part 1 of the rebaseline done in http://trac.webkit.org/changeset/119285
Part 2 done in http://trac.webkit.org/changeset/119295.
Fixed most of these in r120341. Removed all of the rebaselining in r120746 except one: compositing/layer-creation/spanOverlapsCanvas.html Retitled bug.
