WebKit1 on Mac has some logic for this. WebFrameLoaderClient::provisionalLoadStarted() turns off drawing, and it gets turned back on via WebFrameLoaderClient::dispatchDidFirstLayout() and WebFrameLoaderClient::frameLoadCompleted(). This leaves stale pixels on the screen while the new page is early in the loading process, preventing a flash between pages.
