Comment 0 for bug 1774505

When watching a movie on an external display it's often useful to adjust the volume. Currently gnome-shell will display the OSD on both displays creating an overlay over the video. Unity would only display on the screen of the app used at the moment. Ideally it would just always show up on the main display so that you can keep focus on the video app for other keybindings to still work. I tried searching for an extension to do this but couldn't find one.
