Quite frequently, Safari windows expand so that their lateral borders are beyond the edges of my screen. Shrinking them by clicking the amber menubar window, then expanding them again doesn’t help.

Is there some magic I can invoke to confine the windows to the actual size of my screen?

I’m also wondering whether it’s possible that because I populated this device using the Migration Assistant FROM a 16” MacBook Pro (Intel, 2020), whether there might be some display preference copied from that laptop that is causing this.

I should note also that some other apps; e.g., Mail sometimes display the same behavior.
