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