I tried with Python3.6 and got similar output.

This may be relevant: https://stackoverflow.com/questions/34710835/proper-way-to-shutdown-asyncio-tasks

have you try python 3.7 ? BTW there is a trouble when window is closed ... and I will investigate that thanks for report

@icarito btw, can you try with python3.7 ? module 'asyncio' has no attribute 'all_tasks' in all python <3.7

For me, it works as expected
