      for our project, we need to fully customize the window. to achieve this, we create a frameless window and draw a fake titlebar on the frameless window.

      but we found out that frameless Qt app under mac can't perform maximize and minimize.

      in the attachment, you can find a simple app that reproduces the issue. there is a button on the frameless window, click that button will call showMinimize(), but the window stays.

      but the same app works on windows.
