Recently the open windows I am using on the desktop (one or several) suddenly move to the left and off the screen. This is a new phenomenon. Is it something I am doing and how do I get them back? I am using a 2017 MacBook Pro.

MacBook Pro 13″, macOS 10.15

I don't fully grok the scenario you are trying to describe..


old issue, new issue, what changed?

Does not sound like any kind normal that I ever heard of....


Use apps in full screen on Mac - Apple Support


Use Mission Control on your Mac - Apple Support



if no insight or resolve—

Try a SafeBoot How to use safe mode on your Mac - Apple Support


Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.




To trouble shoot further you can:


—Test issue in another user (or guest user) account Set up users, guests, and groups on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account. 



Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS
