    Description

      The QTreeWidget is rendering poorly when the frame style is set to QFrame::Plain | QFrame::Box while using the Windows 11 style.
      To reproduce the issue, run the attached project and click on "QTreeWidget Bugs" button.
      A detailed description is in the dialog itself.

      Here also some reproducer for QTableView showing grid lines before:

      int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QTableWidget tw;
    tw.setColumnCount(5);
    tw.setRowCount(5);
    tw.setItem(0, 0, new QTableWidgetItem(app.style()->name()));
    tw.show();
    tw.setShowGrid(false);
    return app.exec();
}

      Result after the current patches:
