QTableView doesn't repaint properly

Message 1 in thread

Hi,
After adding a row in a QTable view
(
bool ProfileModel::insertRow(int position, const QModelIndex &parent)
{
        beginInsertRows(QModelIndex(), position, position);

        Profile p("");
        profiles.insert(position, p);

        endInsertRows();
        return true;
}
), the row is added but the hidden part of the vertical header (the part that 
is shown by scrolling the QTableView) is not properly rendered before it is 
repainted by any event (another window goes over it or the window is 
minimized,...)

I attached a sreenshot to get wath I'm talking about :-)

Is that normal ? Is there something to do to avoid that ?

In advance, thanks.

Detlev.

What version of Qt?  Have you tried against snapshots?

It's Qt 4.3.0. I didn't try any snapshots but I try to keep this version up to 
date.
