Vulkan RenderPass Incompatible

[Vitriol1744]

Hello,

When i am draging imgui window outside of my main window, i get bunch of errors from validation layer about incompatible renderPass. I saw pull request that was fixing this error here - #3522. but for some reason this error occurs for me. i am using the latest version of imgui docking branch

my initialization imgui code:
`::ImGui::CreateContext();
::ImGui::StyleColorsDark();

    VkDevice device = VulkanRendererAPI::GetDevice().GetLogicalDevice();
    static VkDescriptorPool descriptorPool = VK_NULL_HANDLE;

    VkDescriptorPoolSize poolSizes[] =
    {
        { VK_DESCRIPTOR_TYPE_SAMPLER, 1000 },
        { VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER, 1000 },
        { VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE, 1000 },
        { VK_DESCRIPTOR_TYPE_STORAGE_IMAGE, 1000 },
        { VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER, 1000 },
        { VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER, 1000 },
        { VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER, 1000 },
        { VK_DESCRIPTOR_TYPE_STORAGE_BUFFER, 1000 },
        { VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC, 1000 },
        { VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC, 1000 },
        { VK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT, 1000 }
    };
    VkDescriptorPoolCreateInfo poolInfo = {};
    poolInfo.sType = VK_STRUCTURE_TYPE_DESCRIPTOR_POOL_CREATE_INFO;
    poolInfo.flags = VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT;
    poolInfo.maxSets = 1000 * IM_ARRAYSIZE(poolSizes);
    poolInfo.poolSizeCount = (uint32_t)IM_ARRAYSIZE(poolSizes);
    poolInfo.pPoolSizes = poolSizes;
    vkCreateDescriptorPool(device, &poolInfo, VulkanAllocator::Get().callbacks, &descriptorPool);

    ImGuiIO& io = ::ImGui::GetIO();
    io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable;
    ImGui_ImplGlfw_InitForVulkan(reinterpret_cast<GLFWwindow*>(mainWindow->GetNativeHandle()), true);
    ImGui_ImplVulkan_InitInfo initInfo = {};
    initInfo.Instance = VulkanRendererAPI::GetVulkanInstance().instance;
    initInfo.PhysicalDevice = VulkanRendererAPI::GetDevice().GetPhysicalDevice();
    initInfo.Device = device;
    initInfo.QueueFamily = VulkanRendererAPI::GetDevice().GetGraphicsQueueFamily();
    initInfo.Queue = VulkanRendererAPI::GetDevice().GetGraphicsQueue();
    initInfo.DescriptorPool = descriptorPool;
    initInfo.MinImageCount = 2;
    initInfo.ImageCount = 2;
    initInfo.Allocator = VulkanAllocator::Get().callbacks;
    VkRenderPass renderPass = VulkanGraphicsPipeline::GetBound()->GetRenderPass();
    ImGui_ImplVulkan_Init(&initInfo, renderPass);

    VkCommandBuffer commandBuffer = VulkanRendererAPI::GetCommandBuffer();

    VkCommandBufferBeginInfo beginInfo{};
    beginInfo.sType = VK_STRUCTURE_TYPE_COMMAND_BUFFER_BEGIN_INFO;
    beginInfo.flags = VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT;
    vkBeginCommandBuffer(commandBuffer, &beginInfo);

    vkEndCommandBuffer(commandBuffer);

    vkQueueSubmit(initInfo.Queue, 1, &submitInfo, VK_NULL_HANDLE);
    vkQueueWaitIdle(initInfo.Queue);

my render code:
`ImGui_ImplGlfw_NewFrame();
ImGui_ImplVulkan_NewFrame();
::ImGui::NewFrame();
IRendererAPI::BeginRenderPass();
ImGui::Begin();
::ImGui::SliderFloat4("Clear Color", reinterpret_cast<float*>(&color), 0.0f, 1.0f);
bool demoWindow = true;
::ImGui::ShowDemoWindow(&demoWindow);
ImGui::End();
//IRendererAPI::DrawIndexed(vertexBuffer, indexBuffer, 6);
IRendererAPI::EndRenderPass();

    ImGuiIO& io = ::ImGui::GetIO();
    if (io.ConfigFlags & ImGuiConfigFlags_ViewportsEnable)
    {
        ::ImGui::UpdatePlatformWindows();
        ::ImGui::RenderPlatformWindowsDefault();
    }

::ImGui::Render();
VkCommandBuffer commandBuffer = VulkanRendererAPI::GetCommandBuffer();
ImGui_ImplVulkan_RenderDrawData(::ImGui::GetDrawData(), commandBuffer);`
