Created attachment 263334 [details] Screenshot of the issue. Reproduced with WebKitGTK+ 2.10.0 and with Safari 7.1 on OS X Mavericks. Steps to reproduce the problem: =============================== Open the URL: https://rawgit.com/tanty/design-hodgepodge/master/svg/filter/feBlend-feImage-resized-tests.html What is the expected behavior? ============================== All the SVGs are shown as the included PNG as reference What went wrong? ================ The feImage in the SVG documents explicits values for x=0, y=0, width=172.8%, height=172.8%, which is the same value than the embedded document's height. Only the SVG in which the embedded SVG document specifies a "viewBox" with values "0 0 <SVGWidth> <SVGHeight>" which, AFAIK, are the default values for the viewBox, is rendered correctly. The SVG in which the viewBox is not provided for the embedded SVG document is not displayed properly since it is not scaled.
