Updated the Skipped list in http://trac.webkit.org/changeset/119279. However, I am a bit worried about it, since at least one of the tests I had to add to the Skipped list seems a bit out of place (compositing/iframes/overlapped-nested-iframes.html). Maybe some of these tests are causing failures later on?
I would be curious about how different the two rects are. Is this just rounding error, or something more serious?
For those watching at home: Simon and I looked at one of these in the debugger briefly. The rects were very different (one was at 0,0 with size 50,50, the other at 18, 20-something with size 100,100). The tests don't assert when loaded into MiniBrowser, so maybe this is something related to DRT?
Probably the same underlying cause as bug 92464.
