Out of curiosity, I am trying the vkQuake snap.
I cannot make it work, it complains with:
QUAKE ERROR: Couldn't create window: Installed Vulkan doesn't implement the VK_KHR_surface extension.
I have an Intel HD620 laptop, I have I know vulkan is working fine, this is the only app having problems.
Does snaps support Vulkan out of the box? Should some interface be connected?
