Created attachment 189677 [details] Test Case Reduction Redraws for fixed backgrounds don't appear to be triggered automatically when applied to the same DOM node as a 3D CSS transform. Steps to Reproduce: 1) Apply 3D CSS Transform to same node as a fixed-attachment background. (see attached test case for example) 2) Scroll down. 3) Force a redraw (partial or whole). This can be done by (a) selecting text within the bounding box for a partial redraw or (b) resizing the window for a full redraw Actual Results: Visual tearing for partial redraws, and complete repositioning of background for full redraws. Expected Results: Background should behave as background-attachment: fixed, staying in one place while you scroll.
