I am currently developing a Qt application which has a window and a serial port module.

My problem is that when I press on the window or move it, the reception of the QSerialPort module (with the readyRead() signal) is blocked. The reception only resumes when I stop acting on the window.

It seems that this is a known problem: https://bugreports.qt.io/browse/QTBUG-34946

However, I am currently in version 5.15.2. Where do you think the problem can come from and what could be the solution?
