This warning appears when a program tries to use Vulkan (a modern graphics API) on an Intel Ivy Bridge GPU (HD Graphics 2500/4000, from 2012–2013).
Mesa’s intel Vulkan driver (ANV) enables Vulkan on these old GPUs, but not all Vulkan features are implemented due to hardware limitations. The warning is informational – it does not prevent the app from running, but some Vulkan apps/games may crash or render incorrectly.

| Your goal | Action | |-----------|--------| | Ignore warning | Do nothing | | Hide warning | 2>&1 \| grep -v "incomplete" | | Run a Vulkan game | Force OpenGL backend (see above) | | Full Vulkan support | Upgrade GPU |

If you name a specific app/game you’re trying to run, I can give you the exact environment variable or command to switch it away from Vulkan.

Impact: Severe. Proton translates DirectX into Vulkan. DXVK (for DX9,10,11) and VKD3D (for DX12) assume a fully compliant Vulkan 1.3 driver. On Ivy Bridge, you will likely experience:

You will most likely encounter this warning in two scenarios:
