I don't understand what you're trying to achieve.
You're blocking the toolkit's main loop, here. If your application
does this, it's broken and needs to be fixed - regardless of what the
cursor looks like.
The cursor is rendered by the Wayland compositor, but the animation is
performed by the toolkit, i.e. it's the toolkit that uploads the
cursor's data to the compositor.
