Unsolved Blurry text in Text component

[gabodev]

Hi!
I have a qml file that has the following code part:

Button {
    id: button
    style: ButtonStyle {
            .
            .    
    }
    label: Text {
        id: text
        renderType: Text.NativeRendering
        verticalAlignment: Text.AlignVCenter
        text: button.text
        font.pixelSize: 16
        font.bold: false
        smooth: true
        color: "white"
    }
}

The problem is that the text looks blurry:

But I noticed that this problem only appears when the main window is maximized, if it is not, the Qt.NativeRendering feature works fine:

I clarify that the qml file integrates it with PyQt.

Do u see this problem with normal Text element as well ? If yes most of the tim issue is with OpenGL library is not updated properly. Please update
