What you did

Ran the 2d bloom example

What went wrong

The following error floods the console endlessly:

2023-05-25T21:58:32.096948Z ERROR wgpu_hal::vulkan::instance: VALIDATION [VUID-vkCmdEndDebugUtilsLabelEXT-commandBuffer-01912 (0x56146426)]

Additional information

I cannot notice anything wrong the actual bloom rendering, it visually looks fine.

Can't reproduce on main

AdapterInfo { name: "Intel(R) UHD Graphics 620 (KBL GT2)", vendor: 32902, device: 22807, device_type: IntegratedGpu, driver: "Intel open-source Mesa driver", driver_info: "Mesa 22.3.7", backend: Vulkan }

This might be caused by gfx-rs/wgpu#3809

I have the same issue, also on Arch linux 6.3.9 with an AMD gpu.

Examples:

• bloom_2d
• bloom_3d

have the same behaviour

AdapterInfo { name: "AMD Radeon Graphics", vendor: 4098, device: 5686, device_type: IntegratedGpu, driver: "AMD open-source driver", driver_info: "2023.Q2.3 (LLPC)", backend: Vulkan }

Error persist on current dev-main 9309d89

@tecbeast42 It seems the validation layer fix was merged in wgpu 0.17.0. Could you test again on the current main, since it uses 0.17.1, and your test was done when it used 0.16.0 ? I couldn't reproduce both on the current main (8efcbf3) and on 9309d89.

[tecbeast42]

It seems to be working fine now. 👍

@alice-i-cecile It seems this can be closed then 🙂
