I have an iMac running macOS High Sierra. Sometimes, when I'm moving the mouse pointer around it will enlarge to 2-3 times the size for about 1 second. It happens a few times per day.
I assume I'm either pressing some key that causes it or I'm moving the pointer over something that triggers it.
What is causing this behavior? Is there a way to disable it? If yes, how do I do so?
