[Bug ?] I think there is some nondeterminism or something weird, or maybe I'm misunderstanding something.

Look at this flow, I take latent, and use it in two identical advanced ksamplers. With noise addition disabled, so I would expect there to be no way to have some variation, but images are different. I think there is some leftover state somewhere.

On somewhat related note, I had a very weird thing happen, but with regular samplers (won't share images as they are a bit more on the racy side). But the thing is I had managed to generate almost identical images (with identical params, might have been even on different days), but one had "over-baked parts", namely faces, while other had proper rendering. And in general, in comfyUI I sometimes get very weird "overbakes", say perfectly sharp solid color blob over face (which was what happened in case before). Initially I though it was just regular overbakes, maybe cfg too high (though those cases are quite distinct from usual "cfg too high"), but the part where I had identical image but one with them, and other without - makes me thing that something somewhere somehow leaks, sometimes, and screw ups images, not deterministically. I would suspect samplers, somehow, as per first paragraph.
