slow on mac
- 
On macOS Sierra, I create a window with Qt. when I drag the corn of the window to resize, the bigger the window is , the slower the resize process. why? @three.zhang said in slow on mac: the bigger the window is , the slower the resize process. why? my magic glass ball tells me you are doing something in your code upon resizing. Is that correct?

LoL!No! 
 After I create the project from qt creator -- new project -- choose template, I do nothig, just run it.

 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.

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