Tweetdeck for example looks horrible because it uses default white browser scroll bars. ( https://tweetdeck.twitter.com/ ) It's one of my primary reasons for not ditching chrome yet ( though I'll be forced to when they screw ad-blocking. ) I know its a petty aesthetic reason but it really draws your eyes to your second monitor having random white bars in between the black layout.
