Three.js - Remove White Border on Alpha Renderer/AntiAliasing

global.js

/* -------------------------------------------------- */
// With Three.js transparent backgound enabled (alpha)//
// and model white textures on dark background        //
// sometimes artifacts pop up on the edges.           //
// To avoid that, slightly raise the clearcolor       //
// opacity instead of disabilng antialias.            //
/* -------------------------------------------------- */

  // Standard Renderer
  renderer = new THREE.WebGLRenderer( {
    antialias: true,
    alpha: true
  });

  // renderer.setClearColor(0x000000, 0); 
  renderer.setClearColor(0xFFFFFF, 0.5); // YAY!

  // DPR calculation
  var maxDPR = 2 // usually between 2 - 3
  var dpr = Math.min(maxDPR, window.devicePixelRatio);
  renderer.setPixelRatio(dpr);
