Streamline VK_EXT_descriptor_heap Bug

[VanKalanchoe]

Hi im trying to integrate DLSS with Streamline and init seems fine since it report all instances and such needed and return DLSS = true. And then i added Evaluate function and i only see a black screen. I tryed many hours to find a solution on what i was doing wrong but couldnt find any. So i checked GITHUB Issues on this repo and found #109 i tryed his temporary solution by adding:

Binding one dummy (empty, 0-binding) `VkDescriptorSet` via `vkCmdBindDescriptorSets` 
on the command buffer immediately before `slEvaluateFeature(kFeatureDLSS, ...)` makes DLSS actually dispatch and 
produce correct output:

// One-time setup
vk::DescriptorSetLayoutCreateInfo layoutInfo{.bindingCount = 0, .pBindings = nullptr};
auto dummySetLayout = vk::raii::DescriptorSetLayout(device, layoutInfo);

vk::DescriptorPoolCreateInfo poolInfo{.maxSets = 1, .poolSizeCount = 0, .pPoolSizes = nullptr};
auto dummyPool = vk::raii::DescriptorPool(device, poolInfo);

vk::DescriptorSetAllocateInfo allocInfo{
    .descriptorPool = *dummyPool, .descriptorSetCount = 1, .pSetLayouts = &*dummySetLayout
};
auto dummySet = vk::raii::DescriptorSets(device, allocInfo).front().release();

vk::PipelineLayoutCreateInfo pipelineLayoutInfo{.setLayoutCount = 1, .pSetLayouts = &*dummySetLayout};
auto dummyPipelineLayout = vk::raii::PipelineLayout(device, pipelineLayoutInfo);

// Every frame, right before slEvaluateFeature(kFeatureDLSS, ...):
vkCmdBindDescriptorSets(cmd, VK_PIPELINE_BIND_POINT_COMPUTE, *dummyPipelineLayout, 0, 1, &dummySet, 0, nullptr); ```
this solved the issue but obiously not intended right i know VK_EXT_descriptor_heap is still new. I wanted to ask if this is a known issue.  And this is fine to use until resolved ? 

here is the commit with everything i did to enable streamline and dlss https://github.com/VanKalanchoe/Noxiouse/commit/a07294ee74d937e55302d18ef6f0d797f229d0ab
