WebGPURenderer&autoClear: Using `renderer.autoClear = false` yields a different effect.

[Jenychen1996]

Description

I have some confusion regarding the use of autoclear in WebGPU.
When I use renderer.autoClear = false in both webgpu_postprocessing_outline.html and webgl_postprocessing_outline.html, rotating the scene does not yield the same rendering effect. It seems that in the WebGPURenderer, some objects or caches are not being properly culled. To address this, I added renderer.clear() in the animate method of webgpu_postprocessing_outline.html, but this still did not resolve the issue.
Could you please guide me on the correct way to use it? Thank you.

Reproduction steps

1.Run webgpu_postprocessing_outline.html or webgl_postprocessing_outline.html
2.Run renderer.autoClear = false in the console.
3.Left-click Rotation Scene

Code

// code goes here
const guiObj = {
  autoClear: true
};

gui.add(guiObj, 'autoClear').name('autoClear').onChange(value => {
  if (renderer) {
    renderer.autoClear = value;
  }
})

if (!renderer.autoClear) {
  renderer.setClearColor(0xffffff)
  renderer.clear()
}
