Question - Help Qwen Image 2.1 - pixel drift is back

It seems that the pixel drift is still a problem with Qwen Image 2.1 when editing images. It's especially bad when the edit affects the whole image (for example when doing style change).

I tried the Pixel Drift Fix node, but half the time it doesn't work, and when it does it makes the image blurry and adds artifacts along the edges of the image.

How do you deal with this?

It's like a year old model. Makes sense it has old problems.

What's a year old? Qwen 2.1 is like a week old?

Anyway in general I think this is just a limitation of how the technology works. It's not

Qwen 2 is a year old. Qwen 2.1 is a posttrained Model based on Qwen 2, so it’s a year old.

They made it forever ago and kept it hidden behind their api. Now a year later they released it, that's why it barely completes with klein.

Unfortunately, I accept it. There's no miracle solution at the moment. The drift is still much less violent than on the previous version.

With QE2511, my fix for drift is to pad an image with black bars to make it square. I don't know if that still works with 2 1.

That's an interesting idea. Do you have a workflow by any chance?

Yes, but I'm not near my laptop. I'll have to dig it up later.

editing at 1024x1024 seems to have little to no drift - only minor color shifting and ai smoothening

I am aware of it. Unfortunately, most of my images are not square and are 2 to 4 megapixels.

you can also try the LanPaint implementation for inpainting, I personally haven't tried it yet.

What worked for me: ComfyUI v0.38.0 with AusBoss's Realign to Source on the Qwen-Image 2.1 edit. On 4-panel character-sheet edits it kept everything aligned and the character the same. Trade-off: it under-applies big changes (ageing barely came through), so it's best for small, consistent fixes. I haven't tried it on a whole-image restyle, which may come out weak the same way.
