Behavior of app windows & mouse

I got a new MacBook Pro for Christmas! Yay! But it's got some behaviors I'm not familiar with.

My question today is about "disappearing" windows. Sometimes when I move my mouse, the window will slide up and to the left, leaving just a small strip showing. I can click on that strip and it comes back, but I'd really like to have this not happen. If I want to minimize a window, I'll click on the yellow dot, otherwise I'd like it to stay open.

Can anyone tell me what's going on here, and where the option controls are for it? TIA for any suggestions.

MacBook Pro 14″, macOS 12.0

Yes, this is a feature of mission control called Show Desktop. It is triggered by a 4 finger outward pinch on the trackpad. There may be a keyboard shortcut set in Mission Control in System Preferences, and you can disable the trackpad gesture in System Preferences > Trackpad > More Gestures > Show desktop. Hope this helps.

Dear a brody,

I went to System Prefs > Mission Control. I didn't see anything that looked like it controlled the behavior I'm seeing.

Here's a picture of what the screen looks like after I've moved the mouse up and to the left. (I just captured the upper 1/3rd, to show the little bit of window peeking out from under the Menu Bar.) (It's that gray sliver.)

You enabled Mission Control. Go to Apple menu -> System Preferences -> Mission control to control what commands enable it.

I looked at the Mission Control area again, and noticed the "Hot Corners" button. I think the settings there are what I need to change, but I don't understand the choices. Any wisdom on this?

I think de-selecting several things in that Trackpad area solved the problem. Thanks!
