Hi,
I'm came here to respond to this thread:
Extensions VK_KHR_surface and VK_KHR_win32_surface have disappeared
I noticed something similar in the Linux driver (16.15.2). The ICD reports the instance extensions:
- VK_KHR_swapchain
- VK_KHR_xcb_surface
but not VK_KHR_surface.
Earlier versions of the LunarG loader would enumerate VK_KHR_surface anyway, and allow it to be used. I bisected to this commit:
loader: ghlvl#79, Fix to not report unsupported WSI surface extension… · KhronosGroup/Vulkan-LoaderA...
which was first released in 1.0.8. After this change the loader will only enumerate VK_KHR_surface if the ICD enumerates it, causing the extension to be unusable. Even the LunarG demos from the loader repo fail with:
"vkEnumerateInstanceExtensionProperties failed to find the VK_KHR_surface extension."
