QFrame background overpaint the content widgets of the layout

[cranberries_]

Hi,
There is a horizontal layout which includes QLabels ( used to dislay images ). I've created a QFrame instance and set its layout to this layout. When I set background color of QFrame to black, QLabels are not displayed. It overpaints the content widgets on the layout.
Could you please help about it ?

Hi,

Can you share how you setup your widgets ?
