Feature: Allow OSD to render on top of fullscreen applications

[russjr08]

Is your feature request related to a problem? Please describe.
Currently, when playing a game that is fullscreen, I am unable to see events that the OSD displays, such as when adjusting the volume or muting/unmuting my Microphone. I can of course tell if the volume itself is changing, but knowing whether the microphone is muted/unmuted is a bit harder to determine (and unfortunately due to keeping track of a game, I lose track of what the last state of the microphone was 😅).

Describe the solution you'd like
I'd love it if there were a setting that allowed the OSD to render on top of fullscreen applications.

Describe alternatives you've considered
I don't have any alternatives for this idea sadly.

Additional context
None at this time.
