after watching a youtube video and closing the tab (or entirely closing firefox for that matter), a snapshot of the video hides in the background of all my windows. seems to reveal itself most in the color black. for instance, i can see parts of it in each letter of this post and see the entire video in a terminal (see attached image - sorry, it doesnt show up in screenshots. had to use my iphone to take the picture).
any ideas or things i can post to help debug?
