The past few days when watching videos on Youtube it will randomly change which video I'm watching. Sometimes it will go backwards and start replaying the video I just finished watching, sometimes it will skip to the next video. Sometimes it happens once, and others it will happen several times in a row. Every time I've witnessed it I haven't been touching my keyboard or mouse, and my curser wasn't on what was selected even if I had bumped it.
Even more annoying is it will do this to a paused video and then just keep playing videos through the autoplay even if I've stepped away from my machine.
