Direct Display does not scale to multiple outputs.

[bsm-sdo]

I could successfully run the sample with one display. However, I am unable to create more than one Vulkan swapchain using Direct Display.

I have three display outputs. All of them are removed from Windows as described. Then I trivially modified the VkDirectDisplay class to create three display surfaces and three Vulkan swapchains instead of one. When the second swapchain gets created, I could observe one of the following behaviour:

• vkCreateSwapchainKHR is successful, but the previous output connection is immediately lost.
• The driver crashes during vkCreateSwapchainKHR.
• vkCreateSwapchainKHR returns with VK_ERROR_INITIALIZATION_FAILED.

Is there a way to create multiple swapchains using Direct Display?
