On YouTube the video will start playing but the rectangle it should be in will still be black, refreshing usually works. Sometimes a video will simply stop playing. Sometimes i have to close all apps and restart the browser twice to get it to work. Sometimes trying to go to full screen will crash the app. Sometimes popping the app out of full screen into a floating window crashes it. This one is new, it's the uploaded screenshot, it crashed mid video and made the video look funny.
