EFL pixel result
It looks like nothing is being rendered after the gray repaint mask. See attachment for details. Most of the rectangle should be light green.
Retitling, the same problem happens with both WK1 and WK2.
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.
