"Flux is disabled for... " notifications for non-disabled apps.
I recently disabled flux for fullscreen apps, and I believe it is since then that it randomly gives me notifications that it is disabled for an app (i.e. Firefox), even though it is not disabled for that app. The colors are unaffected by this.
I tried clicking on the "Flux is disabled for Firefox" notification, and it simply removed the app's name ("Flux is disabled for...") from the notification.
