窗口時DirectX11交換鏈紋理渲染問題？

我編程基於DirectX11的遊戲框架，但我發現了一個問題，我的紋理嚴重屏幕上顯示，這是截圖：窗口時DirectX11交換鏈紋理渲染問題？

Texture shown badly on swapchain initialized to windowed

正如你所看到的圖像不完美，但我注意到，只有當我初始化交換鏈爲窗口，如果我沒有，並且我初始化爲全屏，精靈顯示正確，即使在運行時，我從全屏切換到窗口它仍然正確顯示，這是屏幕上顯示的圖像：

Texture shown correctly on swapchain initialized to full screen and then toggled to windowed

還有就是我swapchain的初始化：

RECT dimensions; 
GetClientRect(game->Window, &dimensions); 

unsigned int width = dimensions.right - dimensions.left; 
unsigned int height = dimensions.bottom - dimensions.top; 

D3D_DRIVER_TYPE driverTypes[] = 
{ 
    D3D_DRIVER_TYPE_HARDWARE, 
    D3D_DRIVER_TYPE_WARP, 
    D3D_DRIVER_TYPE_REFERENCE, 
    D3D_DRIVER_TYPE_SOFTWARE 
}; 

unsigned int totalDriverTypes = ARRAYSIZE(driverTypes); 

D3D_FEATURE_LEVEL featureLevels[] = 
{ 
    D3D_FEATURE_LEVEL_11_0, 
    D3D_FEATURE_LEVEL_10_1, 
    D3D_FEATURE_LEVEL_10_0 
}; 

unsigned int totalFeatureLevels = ARRAYSIZE(featureLevels); 

DXGI_SWAP_CHAIN_DESC swapChainDesc; 
ZeroMemory(&swapChainDesc, sizeof(swapChainDesc)); 
swapChainDesc.BufferCount = DXGI_SWAP_EFFECT_SEQUENTIAL; 
swapChainDesc.BufferDesc.Width = width; 
swapChainDesc.BufferDesc.Height = height; 
swapChainDesc.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM; 
swapChainDesc.BufferDesc.RefreshRate.Numerator = 60; 
swapChainDesc.BufferDesc.RefreshRate.Denominator = 1; 
swapChainDesc.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT; 
swapChainDesc.OutputWindow = game->Window; 
swapChainDesc.Windowed = true; 
swapChainDesc.SampleDesc.Count = 1; 
swapChainDesc.SampleDesc.Quality = 0; 

unsigned int creationFlags = 0; 

#ifdef _DEBUG 
creationFlags |= D3D11_CREATE_DEVICE_DEBUG; 
#endif 

HRESULT result; 
unsigned int driver = 0; 

pin_ptr<IDXGISwapChain*> swapChainPointer; 
swapChainPointer = &swapChain_; 

pin_ptr<ID3D11Device*> d3dDevicePointer; 
d3dDevicePointer = &d3dDevice_; 

pin_ptr<D3D_FEATURE_LEVEL> featureLevelPointer; 
featureLevelPointer = &featureLevel_; 

pin_ptr<ID3D11DeviceContext*> d3dContextPointer; 
d3dContextPointer = &d3dContext_; 

for (driver = 0; driver < totalDriverTypes; ++driver) 
{ 
    result = D3D11CreateDeviceAndSwapChain(0, driverTypes[driver], 0, creationFlags, featureLevels, totalFeatureLevels, 
     D3D11_SDK_VERSION, &swapChainDesc, swapChainPointer, 
     d3dDevicePointer, featureLevelPointer, d3dContextPointer); 

    if (SUCCEEDED(result)) 
    { 
     driverType_ = driverTypes[driver]; 
     break; 
    } 
}

這是切換全屏代碼：

swapChain_->SetFullscreenState(isFullScreen, NULL);

哪裏IsFullScreen是傳遞給containig功能的布爾值。

任何人都可以幫助我嗎？提前致謝！

編輯：

解決：

我已經在我的窗口創建變化WS_OVERLAPPED參數：

RECT rc = { 0, 0, WindowWidth, WindowHeight }; 
AdjustWindowRect(&rc, WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, FALSE); 

LPCTSTR title = Utilities::StringToLPCSTR(Title); 

HWND hwnd = CreateWindowA("BSGame", title, WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, CW_USEDEFAULT, CW_USEDEFAULT, rc.right - rc.left, rc.bottom - rc.top, NULL, NULL, windowHandler, NULL);

要WS_OVERLAPPEDWINDOW

你調整你交換鏈，釋放意見，復位你打電話設置全屏時的視口？ – catflier

不，這是功能; inline void GraphicsDevice :: FullScreen（bool isFullScreen） { \t swapChain _-> SetFullscreenState（isFullScreen，NULL）; } – ThomasSquall

當你調用SetFullScreen你SwapChain，你只需要改變模式。

通常情況下，通話後，你應該從你的主要形式收到WM_SIZE消息，然後需要做到以下幾點：

釋放綁定到您的swapchain任何相關的資源（如：紋理和RenderTargetView）確保你也可以在設備上下文中調用ClearState，因爲如果你的SwapChain仍然綁定到管道，你也會遇到問題（如果綁定到管道，運行時不會銷燬資源）。

下次呼叫調整上swapchain，如：

HRESULT result = mSwapChain->ResizeBuffers(0,0,0,DXGI_FORMAT_UNKNOWN,0);

最後，你可以再次查詢質地：

ID3D11Texture2D* texture; 
mSwapChain->GetBuffer(0,__uuidof(ID3D11Texture2D),(void**)(&texture)); 
//Get Buffer does an AddRef on top so we release 
texture->Release();

，並創建一個新的RenderTargetView，加上更新您的視口的新的大小（從紋理獲取描述）。

我已更新我的代碼，因爲你告訴我，但我獲得相同的，我怎麼能告訴你代碼的帖子？ – ThomasSquall

我認爲你已經明白了相反的情況，在調整大小之前，我在窗口模式下遇到了問題！ – ThomasSquall

在我的情況的問題是窗口創建過程中，這是我的情況：

RECT rc = { 0, 0, WindowWidth, WindowHeight }; 
AdjustWindowRect(&rc, WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, FALSE); 

LPCTSTR title = Utilities::StringToLPCSTR(Title); 

HWND hwnd = CreateWindowA("BSGame", title, WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, CW_USEDEFAULT, CW_USEDEFAULT, rc.right - rc.left, rc.bottom - rc.top, NULL, NULL, windowHandler, NULL);

爲了解決我已經改變了WS_OVERLAPPED到WS_OVERLAPPEDWINDOW
