Microphone indicator (orange dot) in top right corner persists after app closed
I understand that the orange dot should light up next to the control center icon in the menu bar, when there is an app using the microphone (usually Zoom). This works fine on my system, shown below:
However, when I quit the relevant apps, the orange dot moves to the top right corner, and doesn't seem to go away, except after a full restart, like so:
Is this a bug with the indicator light, or does the orange light in the corner (instead of next to the control center) intentionally mean something different? Seems like a bug to me, but not sure if it is known, and want to make sure there isn't a hidden process using my microphone or something.
