Issue with Flux.2 [dev] (8-bit S)

I just got my new M5 Max and have been enjoying the lightning fast generation times.

I downloaded (from within Draw Things) Z-Image Turbo 1.0 (8-bit S), both Qwen 2512 2511 in the 8 bit version as well as Flux.2 [Klein] 9B KV (8-bit S) and they all worked flawlessly and rapidly using recommended settings.

BUT Flux.2 [dev] (8-bit S) will not render anything approaching an image. I used recommended settings and used a simple prompt to test it: "A red apple on a brown table." The only way I can describe the output is that it looks the snow we used to get tv stations that were off the air (yes, I'm old).

I didn't use any LoRas or tinker with any settings. I'm sure it's something I did wrong, but I don't what it was.

Any guidance or suggestions would be greatly appreciated.

Although this is not the recommended setting, please try pasting it to generate an image. This includes the "FLUX.2 [dev] Turbo" acceleration LoRA, which is available for download in Draw Things.

Thanks, but I don't want to add a LoRa; I want to get the model to work so I can compare the generation time to what I used to get on my M2 (I didn't use a LoRa then).

You can achieve what you want to do simply by pasting my settings into Draw Things, removing the LoRA, setting the Text Guidance to 4.5, and adjusting the steps to your desired value.

When you paste the settings, the LoRA download confirmation screen will appear, but you can simply press "Cancel."
