Re: [fxtf-drafts] [filter-effects] What should happen if filter and background-attachment fixed; applied to the same element?

Yes, I think filter result on background-attachement:fixed should render beyond the viewport as it does in every other case. 

I'm not sure if you have a Mac for testing porpose. Safari has a viewport like every browser does. But the window frame on top is transparent and you can see the page content. That does not belongs to the viewport, but background-attachment:fixed; images are rendered there too.
On load when scrollTop is 0: https://i.imgur.com/WcM53Ps.png
When I scroll down you can see that the frame is see through to the background image: https://i.imgur.com/e7aK0nJ.png

So I still think that this is how it should work when background-attachement:fixed; applied: https://jsfiddle.net/3bdv532b/
