QListWidgetItem boundary box only but not highlighted

[tlam]

I'm currently using Qt 4.3.3 on Windows XP 32 bit. I have a QListWidget with the signal currentItemChanged. My QListWidget has a lot of items in it and I have to scroll down to reach items further down the list. Everything is working as expected whenever I select a QListWidgetItem by mouse click or the D-pad. For this list, I can only select a maximum of one item at a time.

Whenever I select a items from the QListWidget without scrolling down, the selected item gets highlighted normally. However,

1)If I select an item
2)then scroll down until I can't see my initial selection
3)select another item in the list

I can see the selection boundary of my current item but it's not highlighted. Any ideas what I might be missing?

I can't reproduce the problem with Qt/X11 4.4.0:

#include <QtGui>
 
int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QListWidget listWidget;
    for (int i = 0; i < 100; ++i)
        listWidget.addItem(QString::number(i));
    listWidget.show();
    return app.exec();
}

#include <QtGui>

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QListWidget listWidget;
    for (int i = 0; i < 100; ++i)
        listWidget.addItem(QString::number(i));
    listWidget.show();
    return app.exec();
}

Can you reproduce the problem with such minimal compilable example?
