imgui render to texture

[matan45]

hi i am trying to render to texture with imgui from this iusse #5110
and i getting this result

the question is why i dont see the clear color i set the on the rendering pass

        ` vk::ClearValue clearColor = { std::array<float, 4>{0.0f, 1.0f, 1.0f, 0.0f} };

	vk::RenderingAttachmentInfoKHR colorAttachment{};
	colorAttachment.imageView = imageFrame.viewPortImageView;
	colorAttachment.imageLayout = vk::ImageLayout::eAttachmentOptimalKHR;
	colorAttachment.loadOp = vk::AttachmentLoadOp::eClear;
	colorAttachment.storeOp = vk::AttachmentStoreOp::eStore;
	colorAttachment.clearValue = clearColor;

	vk::RenderingAttachmentInfoKHR depthStencilAttachment{};
	depthStencilAttachment.imageView = depthStencil.viewPortImageView;
	depthStencilAttachment.imageLayout = vk::ImageLayout::eDepthAttachmentOptimalKHR;
	depthStencilAttachment.loadOp = vk::AttachmentLoadOp::eClear;
	depthStencilAttachment.storeOp = vk::AttachmentStoreOp::eStore;
	depthStencilAttachment.clearValue.depthStencil.depth = 1.0f;
	depthStencilAttachment.clearValue.depthStencil.stencil = 0;

	vk::RenderingInfoKHR renderPassInfo{};
	renderPassInfo.sType = vk::StructureType::eRenderingInfoKHR;
	renderPassInfo.renderArea = { 0, 0, swapchainExtent.width, swapchainExtent.height };
	renderPassInfo.layerCount = 1;
	renderPassInfo.colorAttachmentCount = 1;
	renderPassInfo.pColorAttachments = &colorAttachment;
	renderPassInfo.pDepthAttachment = &depthStencilAttachment;
	renderPassInfo.pStencilAttachment = &depthStencilAttachment;

	commandBuffer.beginRenderingKHR<vk::DispatchLoaderDynamic>(&renderPassInfo, dldi);

	commandBuffer.bindPipeline(vk::PipelineBindPoint::eGraphics, engine->getShader(shaderIndex)->getPipeline());

	vk::Viewport viewport{};
	viewport.x = 0.0f;
	viewport.y = 0.0f;
	viewport.width = static_cast<float>(swapchainExtent.width);
	viewport.height = static_cast<float>(swapchainExtent.height);
	viewport.minDepth = 0.0f;
	viewport.maxDepth = 1.0f;
	commandBuffer.setViewport(0, 1, &viewport);

	vk::Rect2D scissor{};
	scissor.offset.x = 0;
	scissor.offset.y = 0;
	scissor.extent = swapchainExtent;
	commandBuffer.setScissor(0, 1, &scissor);


	std::array<vk::Buffer, 1> vertexBuffers = { vertexBuffer->getBuffer() };
	std::array<vk::DeviceSize, 1> offsets = { 0 };
	commandBuffer.bindVertexBuffers(0, static_cast<uint32_t>(vertexBuffers.size()), vertexBuffers.data(), offsets.data());

	commandBuffer.bindIndexBuffer(indiceBuffer->getBuffer(), 0, vk::IndexType::eUint16);

	std::array<vk::DescriptorSet, 1> descriptorSets = { uniformBuffers->getDescriptorSets()[0] };
	commandBuffer.bindDescriptorSets(vk::PipelineBindPoint::eGraphics, engine->getShader(shaderIndex)->getPipelineLayout(), 0, descriptorSets, nullptr);

	commandBuffer.drawIndexed(static_cast<uint32_t>(indices.size()), 1, 0, 0, 0);

	commandBuffer.endRenderingKHR<vk::DispatchLoaderDynamic>(dldi);`

note i also use the vulkan extension VK_KHR_DYNAMIC_RENDERING_EXTENSION_NAME

Hello,
Do you realize this is 100% a Vulkan question and not a Dear ImGui question?
Consider using RenderDoc (gpu debugger) to understand what is going on.
