For us this shows up with the getCursorScreenPoint method as we poll it to find when the users mouse position is at the edge of the screen. However every time the method is called it leaks a non-insignificant amount of memory.

I've put together a demo here: https://github.com/speak/electron-bug-demos/tree/get-cursor-screen-point-memory-leak - simply run the app and watch the memory usage shoot up. This is what the usage in timeline looks like:

The core code is simply:

this.interval = setInterval(function(){
  var screen = require('screen');
  var point = screen.getCursorScreenPoint();
  console.log(point.x, point.y);
}, 10);

Hopefully someone can point out something stupid I'm doing - I'd prefer that to this being a real bug 😉
