Can I be notified when a Item has finished repainting?

[Stefan Monov76]

I'm making a snapshot (via a ShaderEffectSource with live: false) of an Item, but I'm sometimes (1 cases in 200) getting a blank snapshot. I'm making the snapshot based on a signal like this:

Image {
    onStatusChanged: {
        if (status == Image.Ready) {
            snapshotter.makeSnapshot();
        }
    }
}

This is just as an overall context. I won't post a testcase for now because it's a big app and I haven't yet isolated a testcase. That might be material for a future question.

So I'm not asking "where's the bug in my code" yet. Instead I have a simple question that I think may help me fix the bug:

Can I be notified when a Item has finished repainting?

Rationale: Maybe when I get status == Image.Ready, the Image has merely loaded and not yet painted the loaded data into the offscreen surface. So if my desired signal exists, I could hook onto it instead of hooking onto Image.statusChanged.

Note: I could implement my own NotifyingImage component that works like Image but additionally exposes a repainted signal. But I'd like to know if there's a built-in way.
