Render fails on pixel phones

Description of the problem

My app works on all browsers and equipment we’ve tried it on with the exception of pixel phones. On pixel phones, we get an error on the first call to render, with this stack trace:

texImage2D    @    three.js:19999
setupFrameBufferTexture    @    three.js:20738
setupRenderTarget    @    three.js:20915
WebGLRenderer.setRenderTarget    @    three.js:24430
WebGLRenderer.render    @    three.js:23129
render    @    RenderPass.js:51
render    @    EffectComposer.js:88

I’m not sure which portions of the code would be helpful in tracking this down?

Pixel Phone

I was able to track it down to this line:

renderer.setPixelRatio( window.devicePixelRatio );

in case anyone else experiences the issue.

Definitely helps. Without that context, other users would just blindly remove setPixelRatio().
