Re: "My email (mail app) is being screen recorded and going into split screen"
Wondering if updating the MacOS to the newest version may help (NB: Wise to back up Mac first if updating )
(In MacOS 15.6 Apple provided important bug fixes and security updates.)
Else, if already using MacOS 15.6:
You might want to check whether you have given any apps (eg: social media) permission to send you notifications, or such that split screen and / or if you allow apps or websites to use your camera (screen recording).
Eg: Go to System Settings > Notifications to check which apps, if any, you allow to send notifications.
Go to System Settings > Privacy and Security > Camera to check if apps allowed access your camera.
Open Safari: Click Safari > Settings > Websites > Camera to check if websites can access your camera
