    Question grab() QTextEdit is different between linux and windows

    I've changed the background color of QTextEdit throught setStyleSheet().
    Qt Code:
    1. QTextEdit tempEdit;
    2. tempEdit.setStyleSheet( "background-color:black;" );
    To copy to clipboard, switch view to plain text mode 

    and render()
    Qt Code:
    1. QPixmap resultPixmap( QSize(640, 480) );
    2. tempEdit.render(&resultPixmap);
    To copy to clipboard, switch view to plain text mode 
    or grab()
    Qt Code:
    1. tempEdit.grab().save("temp.png");
    To copy to clipboard, switch view to plain text mode 

    It worked perfectly at Ubuntu 18. (temp.png was saved just the way it looked)
    But background color was NOT changed at windows 10. It keeps white background. never changed.

    setPalette() is not what I want. I want change the currently looking style of QTextEdit.

    Can I get an advice?
