Disappears information from QTableWidget when minimizing the window when working in a Windows 8.1 environment.

Hi!
I ran into this problem:
When minimizing the window, the information from QTableWidget (Qt 5.15, C++) disappears, it is when working in a Windows 8.1 environment (in Linux, the same program works without problems).

I filled in the table cells like this:

        QTableWidgetItem *newItem_fmt = new QTableWidgetItem(fmt_qstr);
        ui->tableWidget->setItem(numRows, 1, newItem_fmt);

The full code is here (filling in the table starts with line 349):
