As I have now tested this in several systems, I'm sure it is there, but you don't see it.

There is no zombie process. (on exit the QT app crashes with an access violation (as per the above posted strace log) and continues to run normally in ram after the window closes).

With the normal "top" you most of the time don't see it, because it is way below.

To see it, you need a task manager that you can sort alphabetically, and look for the app file name (the process runs as the app file name).

Or, you can also:

1. open the QT app
2. note down the proccess PID
3. run "top -p PID" : you will see the process alone
4. close the QT app window
5. you will see the process still running

You can also :

1. run "strace dmmediaconverter-qt"
2. close the app window
3. you should see an access violation in the log

This was tested with the qt-pascal binding lazarus IDE library version qtpas 2.6.r61322, qt 5.13.2 and 5.14 and kdeframework 5.65 and 5.66.
