React native new architecture not showing anything

[jb-san]

Im trying to run @react-three/fiber in a new expo project that is using the new architecture, but it does not show anything and when adding object like lighting it causes threejs to throw cannot read trim of undefined

it renders on web and android

I created a repro repo here:
https://github.com/jb-san/expo-52-three-fiber
run:

npm I
npm run ios

it has 3 pages

1. using expo-gl and only threejs (works)
2. using expo-three (works, but it does have a dependency on a lower threejs version, but even forcing the latest version works)
3. using @react-three/fiber/native, (doesn't work)

I can get the PureThree.tsx to not render anything if I remove the style:{} on line 14

trying to make a custom renderer like this

 <Canvas
      style={{ flex: 1, backgroundColor: "black" }}
      gl={(canvas) => {
        const gl = canvas.getContext("webgl", { antialias: false })!;
        const renderer = new THREE.WebGLRenderer({
          canvas: {
            powerPreference: "high-performance",
            antialias: true,
            alpha: true,
            width: gl.drawingBufferWidth,
            height: gl.drawingBufferHeight,
            style: {},
            addEventListener: (() => {}) as any,
            removeEventListener: (() => {}) as any,
            clientHeight: gl.drawingBufferHeight,
          },
          context: gl,
        });
        renderer.setPixelRatio(1);
        renderer.setSize(gl.drawingBufferWidth, gl.drawingBufferHeight);

        return renderer;
      }}
      style={{ flex: 1, backgroundColor: "red" }}
    >...

to mimic the way the renderer is created in PureThree.tsx does not work

Same issue

[jb-san]

After some digging, looks like it is running the renderer, updated my repo with an example where you can see that a useFrame is being called. I might be wrong, but I think there is something in the react-reconciler that is not working correctly with the new architecture

I have tried to find out why, but from logs it looks like the reconciler works, but I can not figure out why it wont render
