Vulkan创建逻辑设备偶发返回VK_ERROR_FEATURE_NOT_PRESENT错误

当使用自定义类封装窗口类和Vulkan类时，调用vkCreateDevice会返回VK_ERROR_FEATURE_NOT_PRESENT错误，但将类中的相同代码移至main函数中时，却能完全正常运行。此前调用SDL_Vulkan_GetInstanceExtensions获取实例扩展时，也遇到过类似问题。

可正常运行的main.cpp #

window.createWindow();
engine.window = window.window;

try {
    engine.initialize();
}
catch (XiError error) {
    std::cout << "Error " << error.code << ": " << error.definition << std::endl;
}

window.instance = engine.getVkInstance();

VkPhysicalDeviceProperties deviceProperties;
vkGetPhysicalDeviceProperties(engine.physicalDevice, &deviceProperties);

std::cout << deviceProperties.deviceName << ", Driver Version " << deviceProperties.driverVersion << std::endl;

try {
    window.createSurface();
}
catch (XiError error) {
    std::cout << "Error " << error.code << ": " << error.definition << std::endl;
}
window.mainLoop();

vkDestroyDevice(engine.logicalDevice, nullptr);

vkDestroySurfaceKHR(engine.instance, window.surface, nullptr);
vkDestroyInstance(engine.instance, nullptr);

SDL_DestroyWindow(window.window);
SDL_Quit();

无法正常运行的main.cpp #

try {
    app.run();
}
catch (XiError error) {
    std::cout << "Error " << error.code << ": " << error.definition << std::endl;
}

VkPhysicalDeviceProperties deviceProperties;
vkGetPhysicalDeviceProperties(app.engine.physicalDevice, &deviceProperties);

std::cout << deviceProperties.deviceName << ", Driver Version " << deviceProperties.driverVersion << std::endl;

app.window.mainLoop();
app.shutDown();

app.run()实现 #

window.createWindow();

engine.window = window.window;
engine.createVulkanInstance();

window.instance = engine.getVkInstance();
window.createSurface();

engine.getPhysicalDevices();

engine.selectPhysicalDevice();
engine.createLogicalDevice();

window.mainLoop();

app.shutDown()实现 #

vkDestroyDevice(engine.logicalDevice, nullptr);

vkDestroySurfaceKHR(engine.instance, window.surface, nullptr);
vkDestroyInstance(engine.instance, nullptr);

SDL_DestroyWindow(window.window);
SDL_Quit();

window、engine和app均为自定义类。尝试手动添加各种所需的支持扩展后问题可解决，但这种方法不够优雅且代码量较大。怀疑这可能是作用域相关的异常，但不确定。
