Using feOffset to create multiple layers causes drawing artifacts

Reported by michael....@gmail.com, Oct 31 2016

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36

Steps to reproduce the problem:
1. Create a new filter layer with feOffset
2. Composite or blend with original
3. Create a new filter layer from the result of 2.
4. Composite 2 with 3

What is the expected behavior?
There should be no drawing artifacts

What went wrong?
horizontal and/or vertical line artifacts that migrate across the content when you resize your window: live example here. And screenshot attached.

Did this work before? N/A 

Does this work in other browsers? No
 This also occurs on Safari - so it appears to be a webkit issue. This does not occur in Firefox or Edge

Chrome version: 54.0.2840.71  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 23.0 r0

Note that if you continue to extend the filter by layering additional content using feOffset, the drawing artifacts are present on any additional shapes added by feOffset.
