Hi, thank you for reporting the problem. Which PyQt version do you use?

Hi, thank you for reporting the problem. Which PyQt version do you use?

Sorry for delay in replying. The version is: PyQt5 5.14.1

Its installed with the command:

sudo apt-get install python3-pyqt5 Reading package lists... Done Building dependency tree
Reading state information... Done python3-pyqt5 is already the newest version (5.14.1+dfsg-3build1)
