Created attachment 168209 [details] EFL pixel result The expected result can be found in <http://trac.webkit.org/browser/trunk/LayoutTests/compositing/backface-visibility/backface-visibility-image-expected.png>. I have attached what our current result looks like.
Now renders correctly on WK2. WK1 is still broken because AC is disabled.
Closing this bug because the EFL port has been removed from trunk. If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this.
