Most of the compositing tiling tests are misbehaving when run in Chrome though their layer tree dump produced by DRT / NRWT (--platform chromium-gpu) is similar to Safari's. For example, on Windows, scrolling causes the scroll bar to disappear in certain regions. These failures need to be investigated.
