QSortFilterProxy sorting works on Linux but fails on Windows

Seb Tur

I use MariaDB,
when i run this code on linux all works fine, clicking on the column changes the sorting of the table rows

I was using qt 6.8.

Since 6.10.1 cross-compiled to Windows with MXE when i run this code on windows10 when I click on column i can see the sorting indicators changing but sorting of rows does not happen

void MainWindow::on_PB_stany_filtruj_clicked()
{
    if (!model_stany)
        {
            model_stany = new QSqlQueryModel(this);
            model_stany_proxy = new QSortFilterProxyModel(this);

            model_stany_proxy->setSourceModel(model_stany);
            model_stany_proxy->setDynamicSortFilter(true);

            ui->TV_stany_magazynowe->setModel(model_stany_proxy);
            ui->TV_stany_magazynowe->setSortingEnabled(true);
        }
    QString filtruj_stany;


    if (ui->RB_stany_filtruj_nazwa->isChecked())
        filtruj_stany=" TwrKarty.nazwa like :filter";


    QSqlQuery query_stany;
    query_stany.prepare("SELECT TwrKarty.twr_id,TwrKarty.kod, TwrKarty.nazwa FROM TwrKarty ");
    query_stany.bindValue(":filter", "%"+ui->LE_stany_filtruj->text()+"%");
   query.exec();
    model_stany->setQuery(query_stany);

}

Please provide a minimal compilable example, without sql but a simple qt provided model and no mainwindow as this should not be needed to provide a mre

i verified it, this is qt6.10 bug in windows only

qt 6.9.3 works fine on both Linux and Windows whereas Qt 6.10 (and 6.10.1) has this bug on windows

even more, it not only fails to sort, it also causes a crash ocasionally

@Seb-Tur Is it a static build?

@Seb-Tur This might be due to this then : https://qt-project.atlassian.net/browse/QTBUG-141830
