Question

现在我的游戏目前正在展示一张拉伸到表面上的图像（bmp）。我遇到的问题是在其上绘制文字。

正确绘制文字我想要的方式但是，如果游戏没有处于窗口模式，相反，如果它处于全屏模式，文本将会闪烁，我不能为了我的身材而生活出了什么问题。

int Game::Render(){
HRESULT r;
D3DLOCKED_RECT LockedRect;//locked area of display memory(buffer really) we are drawing to
LPDIRECT3DSURFACE9 pBackSurf = 0;
if(!g_pDevice){
    SetError("Cannot render because there is no device");
    return E_FAIL;
}

if(g_pDevice->BeginScene()){

//clear the display arera with colour black, ignore stencil buffer
//
g_pDevice->Clear(0,0,D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,25), 1.0f, 0);

//get pointer to backbuffer
r=g_pDevice->GetBackBuffer(0,0,D3DBACKBUFFER_TYPE_MONO, &backBuffer); //&pBackSurf

g_pDevice->StretchRect(surface, NULL, backBuffer, NULL, D3DTEXF_NONE);

if(FAILED(r)){
    SetError("Couldn't get backbuffer");
}
r=backBuffer->LockRect(&LockedRect, NULL, 0);
if(FAILED(r)){
    SetError("Could not lock the back buffer");
}

g_font-＆GT; DrawText的（NULL，fps_string，-1，＆安培; font_rect，DT_LEFT | DT_NOCLIP，0xFFAABBCC）; backBuffer-＆GT; UnlockRect（）;

//backBuffer->Release();//release lock

g_pDevice->EndScene();
g_pDevice->Present(NULL, NULL, NULL, NULL);//swap over buffer to primary surface

}
return S_OK;

}

DirectX9文本在全屏但不是窗口模式下闪烁？
