User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0 Build ID: 20171124100500 Steps to reproduce: 1. Open uploaded test case. 2. Scroll down page Actual results: Image does not get covered by text and red div. Expected results: Image with filter background should be hidden as user scrolls. Removing the .parallax { filter: grayscale(100%); } rule works as expected, with the caveat that the grayscale filter is (obviously) not applied. Works correctly when WebRender is enabled.
