Wouldn't the shadow layer invalidation alone have the same performance impact as the current patch (where the layer would need to be uploaded at every scroll offset change)? At least, assuming the shadow isn't dissected into many separate layers.

For example, consider both overhangs being present - one at the top and one on the left. Then there's an L shaped shadow around the corner of the web content area and another drop-shadow from the top. Either this layer would need a full content size layer or very complex logic to manipulate a lot of little layers.

Or am I missing something that would make this more efficient?
