      I created CustomGeometry class base on source of GridGeometry.

      When the application continue to update the properties of that class, the memory usage continue to increase.

      I tried the same situation with GridGeometry, but the result was the same.

       

      Model {
    id: gridModel
    geometry: GridGeometry {
        id: gridGeometry
        horizontalLines: 50000
        verticalLines: 50000 
    }
}

SequentialAnimation {
    running: true
    loops: Animation.Infinite
    NumberAnimation { 
        target: gridGeometry
        property: "horizontalLines"
        to: 100000
        duration: 1000
    }
    NumberAnimation { 
        target: gridGeometry
        property: "verticalLines"
        to: 100000
        duration: 1000
    }
    NumberAnimation {
        target: gridGeometry
        property: "horizontalLines"
        to: 50000
        duration: 1000
    } 
    NumberAnimation { 
        target: gridGeometry 
        property: "verticalLines" 
        to: 50000 
        duration: 1000
    }
}

      How to free the memory each time?
