The attached "sample1227" is a sample code from the customer, with which you can reproduce the issue. (Password will be shared in internal comment)

Issue:

• 2D view shows the preview in a different way between "App.qml" and "Screen01.qml".
    Prease refer to the attached screenshots.
    (Sample1227_2DView_from_Appqml.png, Sampe1227_2DView_from_Screen01qml.png)

• Although there may be some mis-implementation in C++ side or QML side, it would be expected that 2D view should be consistent, independent from where it is launched.
