WebGPURenderer: Multiple renderer setup with FX produces warnings.

[didibr]

Description

I’m trying to create 2 different scenes with 2 different webgpus and 2 different postprocess, they give an error when using postprocess.

Reproduction steps

1. create a class to create a webgpu scene
2. use this class and create 2 webgpu
3. when use postProcess, three fails

Code

//If disabling postprocess with normal render works on 'update()'
   //project.postProcessRender.renderAsync(project.scene, project.camera);
    //default render
    project.renderer.renderAsync(project.scene, project.camera);

//or if enable only one webview work too
//create a project WebGPU2
var project2=new Project();
var element2=document.getElementById('div2');
//project2.init(element2);
