my magic glass ball tells me you are doing something in your code upon resizing. Is that correct?

@raven-worx Would you test it on your mac?
@three.zhang
i don't have a modern Mac at the hands right now.Are you sure that this problem is related to Qt applications only? I mean i would suspect a general Mac window manager issue here.
Can you try if other apps also have the same issue? -
No, other apps is normal, just qt apps encounter this problem.

From the web page: https://discussions.apple.com/thread/7685534?start=0&tstart=0 , other people also claimed that resizing some of window is slow. Following programs are mentioned
iTunes helper

I am not sure but I think there might be a common factor.
