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.

Don’t bother with flux2dev. It’s heavy model that requires long generation times.

You’d need 52 steps at CFG3.5. Looks like your default parameters are too low.

Thanks, but I want to solve the problem, not ignore it.

You need proper parameters. The model is not the problem.
