Thanks for confirming, @d.s.cobb! That's exactly the faulty behavior I had reported via Apple Feedback.

Here, it's a Mac Mini M2 Pro with a Dell UltraSharp 40" monitor (U4021QW). And that turned out to be the problem.

As suggested by Dell, I had installed Dell's DDPM software, and allowed it to open automatically on startup. That software has a feature called EasyArrange which allows, among other things, window tiling just like in Sequoia. I've never used it, though, and wasn't aware it was seemingly turned on (maybe it wasn't). For more than a year, it hasn't caused any issues.

Now that changed when updating to Sequoia. Don't ask me how this is possible, but the new macOS window tiling feature seems to have enabled the DDPM EasyArrange feature, with no way of disabling it.

From there on, fixing the issue was easy: Quit DDPM, and the nasty behavior immediately goes away. Go to Settings, Login Items & Extensions, Open at Login, and remove DDPM, so that it doesn't load on startup. Problem solved. This also explains why most people in this thread didn't encounter the problem the way I did.

The exact option to disable is Desktop & Dock > Windows > Drag windows to menu bar to fill screen

Thanks dialabrain.

I am using Sequoia 15.1.1....

• Go to System Settings >
• Dock and Desktop >
• Go the 'Windows' section in the middle >
  • Turn off "Drag Windows to menu bar to fill screen".
  • Turn off "Drag windows to screen edges to tile."

System Settings > Desktop & Dock > turn off "Drag windows to menu bar to fill screen"

Looks like this has changed a little.

It is now under System Settings > Desktop & Dock > Windows "Drag windows to menu bar to fill screen"

The option regarding disabling Tiling options in System Settings, Desktop and Dock, Windows, was not available to me. Sequoia 15.1.1 iMac. In Windows in System Settings I found, "Drag windows to menu bar to fill screen." I seems I was having trouble when moving windows because I was moving too far up to the top of the screen when dragging. I turned this option off. Seems to be OK now.

If you don't use a Dell monitor, it might be your monitor vendor's software that macOS Sequoia plays fancy tricks with. Good luck sorting it out! (I'll post an addendum on Apple Feedback so they're aware of this problem.)

At least for me in 15.1, I did go to System Settings --> Desktop and Dock --> Windows, but my main aggravation was solved by unchecking "Drag windows to menu bar to fill screen". Thanks for pointing the way, dialabrain!

This worked for me thanks to GPT

Turn off Window Snapping (macOS Sonoma & Ventura)

1. Go to  Apple menu → System Settings.
2. Select Desktop & Dock in the left sidebar.
3. Scroll down to the Windows section.
4. Toggle “Displays have separate Spaces” and “Stage Manager” if you don’t want them, but the key setting is:

• Uncheck “Tiling & snapping” (or disable “When dragging windows, enable snapping” depending on your version).

This stops windows from auto-resizing when you drag them to screen edges.

The issue seems to have been solved for me by disabling "Drag windows to menu bar to fill screen" in Desktop & Dock settings

I did that long ago - but it did NOT help. For some reason my browser windows, Xcode windows, BBEdit windows suddenly "maximized" when I mistakenly dragged the windows too close to the top or left/right edge of the screen.

Only when I completely turned off EVERYTHING there ("Tile by dragging windows to screen edges", "Hold option key while dragging windows to tile" and "Tiled windows have margins") -- only then the dreaded "feature" seems to stop.

if you're running any form of 3rd party window tiling SW - e.g. Dell's DDPM utility that they distribute with their monitors - try uninstalling that and see what happens. That was the problem for a couple of us. Don't know if other tiling utilities might suffer from the same fate.

Good luck!
