Describe the bug

On MacBook native display, macOS Tahoe's brightness meter is always empty, even when adjusting brightness. These happens when MonitorControl is either open or quit.

Steps to reproduce

I am still trying to figure out how to reproduce the problem. It has happened a few times already but I have no idea how to reproduce it at the moment. Restarting the computer temporarily fixes the issue.

Expected behavior

On MacBook native display, macOS Tahoe's brightness meter should show the current brightness when adjusting brightness.

Anything else?

@waydabber this might be related to https://github.com/MonitorControl/MonitorControl/issues/1798. In the meantime, I'm trying out BetterDisplay and it seems to solve all my Tahoe related issues. Thanks for the suggestion.

Yes, it's the same as 1798 - this might happen if the app is using software brightness control for some reason.
