After talking to Simon I agree the better approach here is to freeze the layer tree during loading, similar to what we do in WebKit2 to prevent flashes when navigating away from a composited page. I'm going to do this in three steps: - Consolidate the two Mac code paths that install run loop observers for layer tree syncing into a single class that has the ability to install and uninstall the observer. - Add the layer tree freezing logic for Mac WebKit1 and WebKit2 using this new class. - Add a separate implementation for Apple's Windows port, which uses a different mechanism for layer tree syncing.
