GitHub issue: https://github.com/Comfy-Org/ComfyUI/issues/16711

Not run

INT8 attention returns noise on an AMD RX 7900 XT for longer prompts with Qwen-Image 2.1.

What Badgr ran

Nothing was run: the issue is specific to AMD gfx1100 on Windows with ROCm, and Badgr's providers offer NVIDIA GPUs.

What came back

  • The reporter says it also reproduces with neutral text of similar length.

The reporter suggests filing it with comfy-kitchen, the kernel library.

Checked 2026-10-15 in Badgr’s local development environment.
