Artifacts on QML Behavior on y only on Linux, not on Win

[Dtron]

Hello together!
Following code generates attached artifacts on the screen when setting y to 0 (so image scrolls down).

import QtQuick 2.0
Image {
    id: signage_even
    x:0
    y:-1920
    height: 1920
    width: 1080
    antialiasing: true

    Behavior on y {
        NumberAnimation {
            duration: 2000
        }
    }
}

(Qt5.15, Pyside2, Python 3.8-11)

Code was testet on Ubuntu 20/22, Xubuntu 20/22 and Fedora on different Intel CPUs. On Windows code works fine and smoothly. Does anybody has an idea how to solve this problem? Thank you very much.
