So I also have this problem with my zte max pro an recently I found a solution. Go into settings-apps-stock Android an clear all data. Nothing mager happens an it stops the problem until it builds again but then you can clear it again. My daughter also has the same phone and it's never happened to her I think it's because I have more apps and more systems running on my home screen an it over loads stock Android try it, it really works an nothing mager happens just no more stock Android interruption.
