QML LinearGradient console log warning

Hi, i'm trying to add a linear gradient to a rectangle. But in doing so i get he following console log: ShaderEffectSource: 'recursive' must be set to true when rendering recursively.

Simple question why do i have to put my linear gradient like this:

Rectangle{
        id: mainRec
        width: parent.width - 15
        height: parent.height - 18
        anchors.centerIn: parent
        radius: 25
    }

    LinearGradient{
        anchors.fill: mainRec
        source: mainRec
        start: Qt.point(0, 0)
        end: Qt.point(mainRec.width, mainRec.height)
        gradient: Gradient {
            GradientStop { position: 0.0; color: "#3B4567" }
            GradientStop { position: 1.0; color: "black" }
        }
    }

instead of:

Rectangle{
        id: mainRec
        width: parent.width - 15
        height: parent.height - 18
        anchors.centerIn: parent
        radius: 25
        
        LinearGradient{
            anchors.fill: parent
            source: parent
            start: Qt.point(0, 0)
            end: Qt.point(parent.width, parent.height)
            gradient: Gradient {
                GradientStop { position: 0.0; color: "#3B4567" }
                GradientStop { position: 1.0; color: "black" }
            }
        }
    }

to avoid the warning mentioned above? Although i'm getting the correct result when adding later more items inside the rectangle i have to do that outside mainRec brackets which i'm not supposed to because that one has to be the main parent.

@onimusha
The LinearGradient element takes the source element for rendering. So if you put the LinearGradient element as a child of that source element it would render itself recursively, as the warning message says.

@raven-worx Oh i see, thanks, plus i just came across this in the docs Note: It is not supported to let the effect include itself, for instance by setting source to the effect's parent. so that explains why.
