Why is defaultViewport ineffective?

Why is the displayed flow adaptive?

Hard to tell without more context since this screenshot barely tells me anything.
Provide either a repro or show me more of your code please ^^

I used these methods to render the process, but the default-viewport seems not to have taken effect. What could be the reason for this?

The rendered effect

I need some actual context, the whole file(s) of code and not just excerpts of some functions you're using.
The screenshot still tells me very little about your setup and what you're doing :/

My current issue is that after setting the defaultViewport and max-zoom, the rendered flow directly displays with the maximum value. Why is this happening?

I can only use "zoomTo(1)" to re-render the scene.
