I did some measurements on mac and Qt-Linux with the following filter combination:

<feFlood result="a" flood-color="red" flood-opacity="0.5" x="0" y="0" width="800" height="600"/>
<feFlood result="b" flood-color="green" flood-opacity="0.5" x="0" y="0" width="800" height="600"/>
<feComposite id="test" in="a" in2="b" operator="in"/>

Mac is unaffected by this change, but Qt is 10% faster (full browser).
