I'd be interested to try this but it fails to boot from the app image for me.

  Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)

On Ubuntu using i3 with vulkan drivers installed.

Do other Vulkan samples work for you (e.g. vkcube)? I was getting this issue on a laptop with both NV and Intel. Problem can be worked around by forcing the Vulkan loader to use Nvidia GPU (by providing `VK_ICD_FILENAMES=<path_to_nvidia_icd.json>`).

This is a problem I did not even know I had. Thanks for pointing it out!
