macOS 扩展屏下，在不同屏幕启动，窗口行为不一致

[L-Super]

环境：

• Mac macOS 14.4.1
• CPU M3
• CLion IDE
• Qt 5.15.14
• 4K分辨率扩展屏

在Mac主屏，使用CLion运行启动程序：

在扩展屏，使用CLion运行启动程序：

即，程序出现在主屏或者扩展屏，窗口将会不一样。

#include "MainWindow.h"
#include "QWKWidgets/widgetwindowagent.h"
#include "ui_MainWindow.h"
#include <QPushButton>

MainWindow::MainWindow(QWidget *parent) : QWidget(parent), ui(new Ui::MainWindow) {
    ui->setupUi(this);
    auto titleLabel = new QLabel("hhhhh");

    auto minButton = new QPushButton("-");
    minButton->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);

    auto maxButton = new QPushButton("[]");
    maxButton->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);

    auto closeButton = new QPushButton("x");
    closeButton->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);

//    setWindowFlags(Qt::FramelessWindowHint);

    auto agent = new QWK::WidgetWindowAgent(this);
    agent->setup(this);
    windowBar = new QWK::WindowBar();
#if defined(Q_OS_WIN32)
    windowBar->setMinButton(minButton);
    windowBar->setMaxButton(maxButton);
    windowBar->setCloseButton(closeButton);
#endif
    windowBar->setTitleLabel(titleLabel);
    windowBar->setHostWidget(this);
    agent->setTitleBar(windowBar);

#if defined(Q_OS_WIN32)
    agent->setSystemButton(QWK::WindowAgentBase::Minimize, windowBar->minButton());
    agent->setSystemButton(QWK::WindowAgentBase::Maximize, windowBar->maxButton());
    agent->setSystemButton(QWK::WindowAgentBase::Close, windowBar->closeButton());
#endif

//    agent->setHitTestVisible(windowBar->menuBar(), true);

#ifdef Q_OS_MAC
    agent->setSystemButtonAreaCallback([](const QSize &size) {
        static constexpr const int width = 75;
        return QRect(QPoint(size.width() - width, 0), QSize(width, size.height()));
    });
#endif

#if defined(Q_OS_WIN32)
    connect(windowBar, &QWK::WindowBar::minimizeRequested, this, &QWidget::showMinimized);
    connect(windowBar, &QWK::WindowBar::maximizeRequested, this, [this, maxButton](bool max) {
        if (max) {
            showMaximized();
        } else {
            showNormal();
        }
    });
    connect(windowBar, &QWK::WindowBar::closeRequested, this, &QWidget::close);
#endif
}

MainWindow::~MainWindow() {
    delete ui;
}

另外，如果图一是正确的预期行为，那么需要自行实现标题栏的拖动？

I have some helpful information. When using extended display, QWindowKit is gonna work properly if your app is launched on your "Main display", but if you launch your application on your "Extended Display" QWindowKit is not gonna work resulting on system setting up the Default Native System Titlebar.
