Unwelcome & frequent expansion of the monitor image and pages.

I had an old 2017 iMac 27 inch that suddenly started expanding the image on the screen as if I had clicked on the 'command' key + the '+' key. It was doing this all by itself. I could get the screen back to normal size only by putting my cursor at the end of the top task bar address and clicking on 'return'. It kept doing this on occasion.

I then updated my computer by purchasing a new Mac Mini M4 and migrated my stuff from the old iMac to the new Mac mini.

Unfortunately, the bad behavior also migrated to the new Mac mini and my monitor screen continues to enlarge on its own requiring me to repeat the actions described in the first paragraph of this question.

I have Bitdefender for my anti-virus and I ran a complete scan. No viruses were detected. I performed 'First Aid' with my disc utility and the Mal-behavior is still happening.

Are there any knowledgable recommendations out there to remedy the problem?

This sounds like new Sequoia behaviour. I'm not sure about the old iMac. That seems too old to run Sequoia.

But if it is the new behaviour, you can turn it off in System Settings > Desktop & Dock. Scroll down to Windows. Make sure the first two items are disabled, like this:

The problem turned out to be due to my own fault. Apparently, when I set up my Magic Mouse, I checked the double tap which gives an instant enlarged display. So with my fingers resting above the mouse, if I inadvertently tapped it, the image magnified. I turned off this feature of questionable value and now all is great.

Thanks anyway for your input. Help is always welcome.
