启用showMenuButton时，navigationInterface 的MenuButton错位。

[kingmo888]

self.navigationInterface = NavigationInterface(
            self, showMenuButton=True, showReturnButton=False)

当启用showMenuButton时，三等号按钮激活位置只在红框（下沿为分界线）下方了。红框下沿的上方，鼠标划过、点击无反应。

其中，

        self.setWindowIcon(QIcon('logo.png'))
        self.setWindowTitle('  PyQt-Fluent-Widgets')

会导致位置重叠。

综合来说，猜测FramelessMainWindow基于QMainWindow，由于自身的layout，ICO、title位置会不准导致的？

[kingmo888]

@zhiyiYo 是否FramelessMainWindow下无法对其logo与title？谢谢。

[zhiyiYo]

你没给主界面的 hBoxLayout 设置顶部 margin，导致标题栏和导航栏按钮重叠了

[zhiyiYo]

或者你就重写主界面 resizeEvent，把标题栏往右移动 60px
