  1. icomment:
    Unfortunately for me, even though the focus is on version 9, 8.6 allowed me to compare (I wouldn't have opened a ticket otherwise).     
    
    At first, I thought it might be due to epoll/kqueue **TIP458** (I don't know if Tk/X11 uses it) but now if you tell me that it's a limitation of Tk on macOS.    
    
    Here is a [GIF link](https://ibb.co/rK8wVzSF) that shows the difference with my Nim program.   
    
    In any case, thank you for considering my request.I consider this to be a limitation on macOS version 9.    
    I would have liked to give a real example in C with the creation of an image, but I am limited in that way too.    
    
    Thank you for your detailed feedback.
