Windows: Flickering of QLineEdit when using setStyleSheet with background-color (Vista style)

      When setting the background-color of a QLineEdit via style sheet, the QLineEdit begins to flicker on mouse-over (on Windows Vista or higher using default style; using e.g. Fusion style does not produce this problem).

      Example code:

      QLineEdit* flicker = new QLineEdit(this);
flicker->setStyleSheet("QLineEdit {background: red;}");
flicker->show();
