Weird graphics with Vulkan

[Can'tGetItWorking]

When using Vulkan I get weird thing like this:
- Squares with colours

- Small flipped image
[attachment=17614]
- Black screen

Any idea how to fix it?

Using the 64bits windows version of 5.0-9176.
My card does support Vulkan and can run other vulkan applications.
DirectX and opengl work correctly.

And your specific card model is...?

That, and make sure you have the latest Vulkan runtime installed.
