When calling `vkQueuePresentKHR`, the specs say that you can make `pResults` point to an array where one result will be written for each submitted swapchain.
However the driver doesn't write to this memory location. For example if you write `0xdeadbeef` to the memory pointed by pResults, then call `vkQueuePresentKHR`, then read from pResults, you will still read `0xdeadbeef`.
