            [chromium] Accelerated Compositing: Artifacts/blink when enabling compositor.
            https://bugs.webkit.org/show_bug.cgi?id=44196
    
            If accelerated compositing enables after a page loads, the dirtied
            portion of the screen will be only a subset of the full screen,
            leading to artefacts. Avoid these artefacts by invalidating the
            visible content rect on compositor initialization.

            (WebKit::WebViewImpl::setIsAcceleratedCompositingActive):
