For some revisions the output of SVG Filters look dull. All filters are affected. It looks like everything got more brighter. I did not investigate which change caused this problem, but I could see it in the webkit nightly from 9/1
Adding more ppl who might know of a commit that could have caused that.
I can't reproduce. What is a URL that shows this?
Regressed in http://trac.webkit.org/changeset/125462.
