Yes, also what I thought.

For me it was as simple as installing mesa-vulkan-drivers and re-launching rx. It is a very nice and minimal editor - well done

Because for being such a minimalist editor, it requires something that a lot of hardware out there doesn't have and that often requires proprietary drivers.. even though it doesn't need it.

It doesn't seem to work for vmware with debian, because vulkan is a pain to get working if it's even possible?
