Hi Guys, I Bought a new Retina 15 Inch Macbook Pro Mid 2015 with AMD R9 Graphic Chip. This laptop is really nice and I already love it deeply. The only thing that concerns me is that when I am on Facebook, the Icon of welt.de doesn't get displayed correctly. It always looks like this, I can even screenshot it. But this happens only to the welt.de Icon. Otherwise I don't have any problems. What is that?
