User level: Level 1 (4 points)My MacBook Pro has started to randomly resize windows then pop them back to full size. I have not changed any of my settings to prompt this, and it seems to be getting worse. I've found the other comments on here with the suggestions for going into System Settings and turning off everything for stage manager and windows, but nothing seems to work.
I'm getting to the point of wanting to chuck my laptop out the door...

—Have you shut down and restarted to compare your results(?)
—Exit full screen and test, go back to enabling the Full screen and compare your results.
—A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies
Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled temporarily.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
verify your software is up to date—The current stable release of Tahoe including bug fixes, security updates is macOS 26.7.1
