on apple mac, running webkit 2 on lion. Makes me think we're probably not getting all of the pixel diffs we should be :).
See also bug 94517, bug 94396.
Checking the output of the latest WK2 build on the Lion builder, I'm not seeing any ImageDiff error messages. Is this bug still relevant?
I think this was fixed at some point around r126189. Closing. We can open a new bug if there are still issues.
