User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20100101 Firefox/8.0 Build ID: 20111104165243 Steps to reproduce: http://cs.sru.edu/~ddailey/svg/feDisplacement4.svg trying to incorporate rect into feImage for use in feDisplacement doesn't render. May be due to graphics acceleration in FF8/Windows 7 (see https://bugzilla.mozilla.org/show_bug.cgi?id=703890#c3 ) since I see other feImage bugs that have been fixed. Also seems to be related to problem at http://granite.sru.edu/~ddailey/svg/feTile.svg in which Chrome sees svg content for feTile, but FF doesn't. Actual results: The feDisplacement doesn't work as it should (as seen in Opera or Chrome or IE/ASV) Expected results: the gradient should distort the content see also discussions at http://tech.groups.yahoo.com/group/svg-developers/message/65168 and http://lists.w3.org/Archives/Public/www-svg/2011Nov/0066.html

It looks like the testcase uses <feImage xlink:href="#r"> (targeting a document fragment), and we don't have that implemented yet -- that's bug 455986.
