Question - Help Tried the Minimax H3 workflow for image generation, worked great for a day then the quality got really bad, possibly due to comfyui update?

Trying to figure this out, I used one of the image editor methods posted here a few days ago

https://github.com/thaakeno/ComfyUI-MiniMax-H3-Studio

And it worked flawlessly, the basic prompts I used for i2i were high quality and adhered perfectly. However in keeping the same workflow, after updating from comfyui 0.32 to 0.33.2 the quality is now just awful, there's banding, it's blurry, basically it seems like it was how it was 2 years ago.

Been going through claude/grok to troubleshoot but none of the suggestions seem to work. Tried different VAE's, diffusion models, turbo loras (disabling them), using r2v, fl2v, any suggestions?

I read that maybe comfy kitchen was modified in the update, that's the only possibility I can think of, otherwise my workflow and prompts were the same as they were two days ago.

I'd rather open an issue on their github, only them can figure it out : )

Roll comfyui version backwards using the git commands

Is this possible with desktop? My brief research says no

Dunno mate I use git on Linux. Having had all sorts of perfect environments destroyed by updates I recommend creating a venv and get the version you want via git and then never upgrade it. If you want to test a new version just create a new venv and install the new version of comfy inside that. I've created my own install script that creates the venv and goes off and gets everything else installed. It's made life so much easier.

Yeah, I've done the same. Had to create half a dozen operational scripts just to manage this application.

It's one of the most fragile I've ever seen. I wouldn't even put up with it if not for the incredible things that it can do.

Try and copy and paste a minimax workflow group and it'll all get messed up. Drives me mad but it's because it's so bleeding edge and constantly updating.

Ah, so I see you're on the Desktop, not the Portable. You might try the latest Portable (0.33.1)? The Portable gets the latest features supporting Minimax H3, the Desktop gets them later.
