Using chromium with vulkan

My system has 2 GPUs: Intel integrated, and AMD RX580. Both of these are found by vulkan-info --summary plus an additional cpu implementation.

Yet, when I try to use chromium with vulkan using $ chromium --enable-features=Vulkan,webgpu, I get:

Warning: vkCreateInstance: Found no drivers!
Error: vkCreateInstance failed with VK_ERROR_INCOMPATIBLE_DRIVER
    at CheckVkSuccessImpl (../../third_party/dawn/src/dawn/native/vulkan/VulkanError.cpp:88)

    at operator() (../../third_party/dawn/src/dawn/native/vulkan/BackendVk.cpp:492)

What I tried:

• Using --gpu-active-vendor-id=0x1001 on the command line to force AMD
• Using --gpu-active-vendor-id=0x8086 on the command line to force Intel
• X11 vs Wayland
• google-chrome (r115) versus ubuntu chromium snap (r114)

Why do vulkaninfo and chromium contradict each other on the existance of vulkan drivers?

$ inxi -G

This discussion suggests using a different AMD driver. It is possible that the application is using an instance extension that is not available on the current driver.

So, 114 and 115 versions would not work.

When trying Google chrome 116.0.5845.32 I get working Vulkan:
