EFL pixel result
The expected result can be found in <http://trac.webkit.org/browser/trunk/LayoutTests/compositing/culling/filter-occlusion-alpha-expected.png>. I have attached what our current result looks like.
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.
