Hi Thiago, if you have a look at the little sample script I attached to my mail you'll see that I'm actually constructing the application object within the function that is executed in the other thread. I do however import PyQt5 modules at the top of my script, and if I move those imports into the function the warning goes away. Does this suggest that PyQt5 itself instantiates a QApplication as a global object ?
