Example Operation fails assertion about vulkano-www HOT 8 CLOSED

I am experiencing the same issue. I am on macOS 10.14.5.

I also tried guide-image-clear.rs and guide-mandelbrot.rs which both export fully transparent images.

I know that vulkan and some version of vulkano are working on my machine as I am able to run the examples from the Nannou project which is vulkano based.

Let me know if I can provide any further info.

I had a friend test the examples on a Windows machine and they work fine there, so it could be related to macOS. The fact that vulkano works in a nannou project is still odd, but maybe it uses an older version of vulkano where this bug isn't present.

Perhaps this is an issue in the Vulkan → Metal translation layer (if you’re using MoltenVK, does the same happen with gfx-portability?).

I can take a look later. Reading the readme is a bit unclear; is gfx-portability a replacement for MoltenVK that I need to install separate from running these examples?

from vulkano-www.

It is a Vulkan implementation on top of gfx-hal, which on Mac uses Metal, so in this sense yes, it is a replacement for MoltenVK. As I don’t have a Mac myself, can’t really help you install it.

I can point you to their releases where you can download the macOS package which contains libportability.dylib dynamic library which you should be able to use instead of the MoltenVK one.

If the problem is caused by a bug of MoltenVK, there is a chance that it will work with gfx-portability (on the other hand, if it is caused by some limitation of Metal, then both of them might have the same problems).

Okay sounds good. I'll see what I can do to run these examples with gfx-portability then.

My brain is still hung up on the fact that I've got vulkan stuff working through nannou's vulkan examples which also use vulkano 0.13 and MoltenVK and I'm having a hard time figuring out why that might be.

I haven't had a chance to try gfx-portability yet, but I did quickly try the triangle example from https://github.com/vulkano-rs/vulkano-examples (cargo run --bin triangle) and it runs just fine with extremely similar code.

Closing this issue for it being 3 years old. It likely is no longer happening. However, please reopen if anyone experiences this still.
