    Description

      QSerialPort doesn't read / write or signal incoming data while there's pretty much any interaction with window title or frame.

      This was not a problem in 5.12 or 5.13 but appears starting from 5.14.0.

      Steps to reproduce the issue:

      1. Run the qt terminal example https://doc.qt.io/qt-5/qtserialport-terminal-example.html
      2. Connect to a device periodically transmitting data via serial
      3. resize the window => no more data is logged until window frame is released.
