Title:
Video playback faintly shows applications behind active browser window
Status in firefox package in Ubuntu:
Confirmed
Bug description:
Ubuntu desktop 18.10, Mozilla Firefox 64.0
To reproduce:
1. 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.
