Three.js奇怪的崩溃使用聚光灯

我使用Three.js在3D视图中渲染一些网格和一个平面。我在场景中添加了一个聚光灯,因为添加这个我在Firefox上遇到了奇怪的崩溃。第一次加载页面时,场景实际上呈现正常。刷新页面时,firefox崩溃了。我设法在firebug控制台崩溃之前截获它:

THREE.WebGLProgram: shader error: 1285 gl.VALIDATE_STATUS false gl.getProgramInfoLog Failed to create D3D shaders. 
THREE.WebGLShader: Shader couldn't compile.

这是我的聚光灯代码:

var spotLight = new THREE.SpotLight( 0xffffff );
    spotLight.position.set( 2000, 1500, 300);
    spotLight.distance = 3000;
    spotLight.penumbra = 1;
    spotLight.intensity =2;
    spotLight.angle = 1.05;                     
    spotLight.castShadow = true;                
    spotLight.shadow.mapSize.width = 4096;
    spotLight.shadow.mapSize.height = 4096;             
    spotLight.shadow.camera.near = 500;
    spotLight.shadow.camera.far = 4000;
    spotLight.shadow.camera.fov = 3000;
    scene.add(spotLight );

奇怪的是:它只会在第二次加载页面时崩溃,永远不会在第一次加载时崩溃!当我删除聚光灯的代码时,它不再崩溃。在谷歌浏览器中,它似乎工作正常。
