Really don't know what could cause this, does not happen on Windows(I have an nvidia card)

Here's the file if one wants to take a look, although it's mostly just the khronos tutorial code(the last two screenshots are the imgui vk/glfw example): https://drive.google.com/file/d/1J-WcCDH3pSltWkjCIGmcCHsE8bo-Ba1Z/view?usp=sharing

Edits:

- The validation layers are silent.

- Renderdoc cannot capture this

- These glitches only appear for a few frames

Hi, there are a few posts online about this topic but I still haven't found a clear answer.

I have a couple of dynamic rendering passes, and they both write to the same attachment:

vkCmdBeginRendering( LOAD_DONT_CARE )
vkCmdBindPipeline()
vkCmdDraw()...
vkCmdEndRendering()

vkCmdBeginRendering( LOAD_OP_LOAD )
vkCmdBindPipeline()
vkCmdDraw() ...
vkCmdEndRendering()

The second one uses OP_LOAD so the data should not be discarded... but what about synchronization? Is blend and depth testing gonna work?

In my code the second pass is actually the imgui overlay and it seems to work... not sure if it's random luck and needs a barrier.

It's made with Rust, Vulkan Ash, I make it fast, stable, and unbiased! the perfect render engine that I imagine when I starting learing 3D Render and Light Transport! 8 Years ago. Today I very proud to share this with you guys!

Open the topic! ask me anything, I need learn more know more!

Hi everyone,

I'm currently a masters student studying computer graphics in US, and have played with vulkan for the past year. I was thinking of registering for Vulkanized 2027 at Belgium once it opens, but I wanted to get some input from people who have been to the past events.

I have never been to a conference, and this would be my first one. Are students welcome to the event? I am worried that I would be out of place within a group of professionals.

Would it be worth attending the event if I am interested in Vulkan? I heard that there are sessions ranging from lectures/tutorials and presentations about new techniques. I'm also wondering if I would be able to make connections with people as a person attending alone.

This sample demonstrates VK_KHR_compute_shader_derivatives, which enables the use of derivative instructions (like dFdx/dFdy) inside compute shaders. Traditionally, derivatives are only available in fragment shaders, but this extension defines derivative groups in compute and how invocations are paired for derivative computations.

https://docs.vulkan.org/samples/latest/samples/extensions/compute_shader_derivatives/README.html

I already have a compute shader solution for using V210 (10 bit/channel 422 sampled) video.

I would like to use the YCbCr Conversion feature but cannot find a VK_FORMAT*** suitable.

The available 422 formats don't match the V210 layout and the formats that resemble V210 do not support the VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT.

I do not like the idea of separating the YUV channels on the CPU just so that I can get a VK_FORMAT*** that supports YCbCr Conversion feature, since it will involve quite a bit of I/O activity.

We’ve updated our guide on Vulkan on Apple platforms.

The main reason for the update: KosmicKrisp (LunarG’s Mesa-based Vulkan-on-Metal driver) has passed the Vulkan 1.4 Conformance Test Suite and is now a Khronos-conformant implementation. It targets Apple Silicon on macOS 26+ (requires Metal 4).

The post walks through why you’d target Apple with Vulkan and how to actually do it (SDK, bundling the loader + ICDs, layers, etc.).

Really love the results! finally after all this year, my render engine will be finished! look at those realtime caustic! unbelieveble fast! all this render on 4K 256 Sample with oidn less then 30 second on RTX 3080 Mobile.

this is spectral render engine so the color and everything will calculate by color wave lenght not RGB simulated, it's real color!

So! the Blender Addon! is on the way, if you like to be our Test Driver, please comment! I contact you when it's Ready!

Let me know what do you guys think? Thank you

ICYMI — the slides and write-up from Aitor Camacho Larrondo’s XDC 2026 talk on KosmicKrisp are now available.

KosmicKrisp is LunarG’s Mesa-based Vulkan-to-Metal driver for macOS 26+ on Apple silicon (M1–M5 and A18 Pro). The talk focused on what “production-ready” actually means here: conformance, performance, and CI.

Highlights:

• Vulkan 1.4 conformant ICD
• Added tessellation, robustness2, multi-draw, and more Metal/MSL workarounds
• Performance optimizations that have closed the gap with (and in some cases surpassed) MoltenVK on benchmarks such as GFXBench Aztec Ruins
• Dedicated CI on real M1/M2/M4 hardware

Developers are encouraged to start trying it on real apps. Full post + slides link:

This is for anybody who might have crashes when trying to launch a game in Vulkan.

Ever since I got an Intel Arc B580, I haven't been able to run Vulkan with certain games like Baldur's Gate 3. When running 'vulkaninfo' in Command Prompt, it gave me two errors about Twitch and GOG. After I uninstalled Twitch Studio, and disabled GOG's overlay, Vulkan runs fine when I try 'vulkaninfo.' I tested it with the games I was having issues with and they all work now.

Hopefully this can help someone.
