The video is full of problems, you can see the 'Quit Safari' not even change to a white font despite having the blue highlight, there are cases of disappearing text in your video too.. There is a lot going wrong in the rendering there for something that is so utterly basic. You don't have to view this frame to frame to see this you can notice it with every day use. The thing is a decade old machine running the same software can do better, even if you analyse it frame by frame, its perfection. We've gone downhill.
