It appears WebGPURenderer also missing initTexture

WebGPURenderer should initialize the texture if it uses copyTextureToTexture automatically.

I also want to call it before display it the first time to init the renderTexture in the memory before drawing on it and avoid extra uploadtime, same for initTexture to avoid upload when it matters.
