All content flashes blank after the GPU process is terminated. This has been the case since at least Chrome 46, and is an unfortunate side-effect of how we draw content on Mac, but it is unlikely to change. The root cause is that we draw content via a CALayer hosted in the GPU process. When the GPU process is killed, we lose this CALayer until the content is re-drawn.
