Description
> Somehow does not render when window gets to a certain size.
> Things that I've noticed:
> - When window is enlarged but grid size is small, it still renders.
> - It doesn't matter if there are 2 `VelloScene2d`, all of them will also not render at the same time.
> - Using CPU makes everything renders again!

> Reporting here as I really can't figure what's the problem here yet.

Research direction
Start with the reproduction in examples/bevy_examples/examples/velyst_demo.rs and run it while enlarging the window and comparing GPU with CPU rendering. Use the reported window-size behavior and the upstream bevy_vello issue as the investigation context; done means the Vello GPU scene continues rendering at the affected size.
