BusyIndicator in ListView Bug?

Dev1337

Hello there guys,

I got a strange thing going on in my ListView.
When the Item is Created the first time the BusyIndicator works normaly.
But if i flick the View and Scroll down and go up again the BusyIndicator is spinning and flickering like a flashlight.

Am i doing something wrong ?
I tryied it in a Loader but same problem again.

this is my Code:

import QtQuick 2.7
import QtQuick.Layouts 1.3
import QtQuick.Controls 2.0
import QtQuick.Controls.Material 2.0
import QtQuick.Controls.Universal 2.0

ListView {
id: listViewOne
width: page.width
height: page.height
topMargin: 10
model: 10
spacing: 10

delegate: FeedItem {
width: listViewOne.width

        BusyIndicator {
            id: busyIndicator
            anchors.centerIn: parent
            running: true
            width: 100
            height: 100
            Material.theme: Material.Dark
            Material.primary: "#FFFFFF"
            Material.accent: "#FFFFFF"
        }
    }

}
