You have to setup the renderer first (setting its size), then the composers. Otherwise the internal render targets of `EffectComposer` will be too small.

BTW: It’s also a good idea to avoid fixed values for `width` and `height`. Try to use the following setting in order to render in the highest possible resolution.
