When --force-compositing-mode is turned on, iframes (in gmail) take the fast path scrolling because they think they can blit to the window. The Chromium compositor only handles the root layer blitting to the window, and so it scrolls and invalidates the contents incorrectly.
An easier approach to fix this in the short term would be to make the compositor take the slow path by changing the "can blit to window" triggers.
