WebGPURenderer: Resize breaks post FX setup in `webgpu_rtt` example #27466

Closed RenaudRohlinger closed 8 months ago

RenaudRohlinger commented 8 months ago

Description

When using a quadMesh to perform a post FX render any resize of the window will break the renderer and render a black screen. I suspect the texture of the new FBO to not be properly bind back once the previous one was destroyed.

Reproduction steps

  1. Run the webgpu_rtt.html example under the WebGL Backend.
  2. Resize the window

Live example

Version

r160

I fixed it on my local. Will push a bit later as I added MSAA support to the WebGLBackend and fixed that issue in the process and I would like to make a better demo. It was related to the fact the framebuffers were never cleared. 👍
