To clarify, I'm able to reproduce this both with Firefox playing back the video in windowed mode and when Firefox plays the video back full screen. As soon as I pause the video (in either mode), the artifact vanishes, so it only occurs during video playback.

Open any application (such as Nautilus file manager, or the terminal emulator) 2. Open Firefox above this application 3. Begin video playback (I've found that it's easier to notice this bug when the video is a dark gray or black. This video worked well: < https://youtu.be/jYFk1O_t43A >) What happens: In the region where the video is playing, you will faintly see the application(s) that are behind Firefox. What should happen: The video should completely obscure any applications that are not above the browser window. I cannot reliably reproduce this bug when the player is in full screen - i.e. it must be in theater mode or normal player.
