    Description

      When QMdiSubWindow is maximized in MDI example then close button looks super tiny and hardly usable. 

      This can be easily reproduced with Qt's MDI example if run on 4k display.

      Run Mdi and create couple of new child sub window and maximize one of the sub window to see this.

      Attached is the screenshot.
