Youtube videos simply do not play; Tumblr images are distorted.
1. When I click on any YouTube video, the page pops up, but the space (where the video is supposed to play) is simply pitch black. The page states that it is done loading, but no content from the video plays. Everything else on the screen is present.
2. The top bar of Tumblr is distorted. Many (if not all) pictures that show up in my feed are distorted and oddly jumbled.
