QML trembling delegate in ListView when scrolling

kernel panic

I am having some problems with trembling/jerking delegate in ListView when scrolling. I created my chat application.

There are different heights of elements (text, audio, image).
But noticed that there are some scrolling issues if the delegate height is larger, for example 10% of the available screen.

I tried to simplify and localize the problem, I thought that the reason for this behavior is several levels in the card of my chat messages.

Unfortunately even I cut off all custom logic and this effect is still happening.

So, does anyone know how to fix this?
Is it possible to smoothly scroll through different delegates?
Thanks, I will be grateful for any help.

Here is a simple example showing the problem.

"thumbnailWidth" property from model.
If I make it persistent everything works fine, but the images can be different and this approach is not acceptable.

ListView {
    id: messagesList
    anchors.fill: parent
    spacing: 0
    //cacheBuffer: 500
    //displayMarginBeginning: 500; displayMarginEnd: 500
    interactive: true
    verticalLayoutDirection: ListView.BottomToTop
    ScrollBar.vertical: ScrollBar {}
    model: testModel
    delegate: Image {
        sourceSize.width: thumbnailWidth
        onSourceSizeChanged: {
            console.log("onSourceSizeChanged: " + sourceSize.width)
        }
        onVisibleChanged: console.log("onVisibleChanged: " + visible)
        fillMode: Image.PreserveAspectFit
        source: "file:////Users/user/Desktop/Screen Shot 2021-03-03 at 10.36.04 AM.png"
        onSourceChanged: console.log("onSourceChanged: " + source)
    }
}

If I uncomment the cacheBuffer or displayMarginBeginning / displayMarginEnd, the effect disappears.

But in any case, this method has a limitation when jerks are visible again (because of a chat may be big).

In my log i see "onSourceSizeChanged" being called.
But "onVisibleChanged" never.

For example:

qml: onSourceSizeChanged: 0
qml: onSourceSizeChanged: 100
qml: onSourceSizeChanged: 100
qml: onSourceSizeChanged: 0
qml: onSourceSizeChanged: 800
qml: onSourceSizeChanged: 800
qml: onSourceSizeChanged: 0
qml: onSourceSizeChanged: 200
qml: onSourceSizeChanged: 200
