There is a good chance that the current master version already fixes this issue, since the copy commands have been rewritten from scratch. Regarding the block size not being defined,...

Is this issue fixed in the new Vulkano 0.30 release?

You'll need to poke shaderc-rs about it.

Would a partial solution be to make the `Vertex` trait take `&self`? Then it would be easy to make a custom type that returns runtime values in the `member` method....

There are no validation errors, even when I set them to display absolutely everything possible. Just some information about available device extensions at load time, which probably isn't relevant. Using...

I've set up a repository at https://github.com/Rua/flicker-demo with a relatively minimal (in Vulkan terms, anyway, hah) example that displays the behaviour for me. There are no pipelines and no drawing,...
