Uncaught TypeError: e.current.gl.render is not a function on change of route

[stephent]

Since updating RTF to 5.0.3 from 4.2.21, I see the following unhandled error when switching routes in my application:

Uncaught TypeError: e.current.gl.render is not a function
Mb @ /[...]/node_modules/react-three-fiber/web.js:157
THREE.Scene: .dispose() has been removed.

This only occurs on changing away from my page that includes RTF, and only if I make the change before my material textures have finished loading.

I'm using useLoader with TextureLoader to load them, along with Suspense. Did something change in 5.x regarding loading textures that I need to change in my code?

Thanks!
