It took me a minute as to why this icon was bugging me so much, then I realized it's because it has a faux background around it and looks like a folder, but with just one big app icon inside of it.
I don't know much about icon design, but I have to think there would have been a way to make this icon meet the standard icon sizes without having the opaque background behind it like folders.
