Open Mission Control

Use any of these methods to open Mission Control:

I'm using a window snapping/resizing app and this feature above, introduced in El Capitan, is being triggered instead. This when I snap a window to the center top of the screen.

Is there a way to turn this feature off?

According to the Reddit thread, Is there any way to disable Mission Control coming up when I drag a window to the top of the screen?, the solution is:

System Preferences > Mission Control

Uncheck "Displays have separate Spaces" then log out and back in again.

It works, I had the same issue & now it's sorted.

Haven't found out how to disable just the window drag activation but you can turn it off entirely with:

Disable:

defaults write com.apple.dock mcx-expose-disabled -bool TRUE && killall Dock

Enable:

defaults delete com.apple.dock mcx-expose-disabled && killall Dock

    Note to other people trying this, this will disable the full screen apps manager entirely, meaning you cannot use ^up to open it or the pinch in gesture. Commented May 15, 2019 at 22:06

As per the Better touch tool config explanation about using it in conjunction with spaces:

defaults write com.apple.dock workspaces-edge-delay -float 2.0; killall Dock

delays the opening of the spaces switcher, allowing for the window resize to take place.
