Since I upgraded to Windows 10 and updated my AMD Catalyst driver to 15.7.1, I noticed that videos on YouTube, Facebook, Vine, etc start off terrible. If you have a look at the screenshot below, you'll get a better understanding of what's going on. The only way to fix this is if I refresh the page or restart the video. This only started happening once I upgraded to Windows 10, and I'm not sure what's going on. I have a 2GB AMD HD Radeon 280 graphics card as well.
