QML Image not visible when QT_QUICK_BACKEND = "software" and coloring effect is applied

XMLWordPrintable

    • macOS

      When 

      qputenv("QT_QUICK_BACKEND", "software");

      is set in the .cpp file.

      And coloring is applied using MultiEffect 

      Image {
        id: icon      
        visible: false  
        height: 64
        width: 64
        sourceSize.height: 64        
        fillMode: Image.PreserveAspectFit        
        source: Qt.url("./settings.svg")
    }    
MultiEffect {
        source: icon
        anchors.fill: icon
        colorizationColor: "blue"
        colorization: 1
        brightness: 1
      }

      The image becomes invisible. Without MultiEffect or the QT_QUICK_BACKEND flag it works fine.

      Also when using Qt5Compat.GraphicalEffects with ColorOverlay

       

       

      Image {
        id: icon
        height: 64
        width: 64
        sourceSize.height: 64
        fillMode: Image.PreserveAspectFit
        source: Qt.url("./settings.svg")
        layer {
            enabled: true
            effect: ColorOverlay {
                color: "blue"
            }
        }
    }

      The same result. The image becomes invisible. Without ColorOverlay or the QT_QUICK_BACKEND flag it works fine.
