It's just embarrassing. Picture this, your windows-using friend is considering trying Linux, and you go on demonstrating your distro of choice to them... you open the browser, go on a youtube page, and what do they see? A video that doesn't stay in sync with the browser windows - now that's just unprofessional. They'll be all like "what's up with this glitchy video" and you'll be forced to explain that the display server is so bad that it's impossible to fix it...
