Created attachment 242533 [details] Safari-Rendering Open the following svg in WebKit: <svg xmlns="http://www.w3.org/2000/svg"> <filter id="f2" filterUnits="objectBoundingBox" primitiveUnits="objectBoundingBox" x="0" y="0" width="1" height="1"> <feFlood flood-color="#ff0000" result="flood"/> <feComposite x="10%" y="10%" width="80%" height="80%" style="color-interpolation-filters:sRGB" in="flood" operator="in" in2="SourceGraphic"/> </filter> <g filter="url(#f2)"> <rect x="0" y="0" width="100" height="100" fill="#00ff00"/> </g> </svg> Result: The region applied on the filter effect <feComposite> is ignored. The red rectangle is displayed at position = (0,0) with size = (100,100). Expected: The red rectangle should be displayed at position = (10,10) with size (80,80). See the attached screen-shots for how Safari and FireFox are displaying the above svg. NOTE: Chrome and FireFox respect the filter effect region and they behave exactly the same.

This is caused because of the bug in calculating the absolutePaintRect of the feComposite filter when the operator is 'in'. This issue is already covered by https://bugs.webkit.org/show_bug.cgi?id=137856. So closing this is a d dupe. *** This bug has been marked as a duplicate of bug 137856 ***
