Bug avec un copier/coller de calque.
Sur le calque niveau 0 d'une image abîmée par le temps, j'ai effectué diverses opérations pour retrouver des valeurs exploitables. J'ai ensuite coupé une partie pour la coller ensuite et après des modifications sur la partie restante (cadrage, niveaux) lorsque j'ai collé la partie collée, celle-ci est venue en sélection décalée par rapport au coupé et sans tenir compte des réglages de luminosité effectués avant. La reprise de toutes les opérations n'a pas donné cette issue qui s'est produite plusieurs fois aléatoirement avec d'autres fichiers.

Bug with copy / paste layer.
Level 0 on the layer of an image damaged by the time I conducted various operations to find exploitable values​​. I then cut and paste part and then after changes to the remaining part (cropping, levels) when I stuck the paste, it came to selecting offset from the cut and regardless of brightness adjustments made ​​before. The resumption of all operations did not give this outcome, which occurred several times randomly with other files.

Is the problem that the pixels you have pasted back into your document are offset from where they were cut? or that something is wrong with the tonal adjustment of the pixels?

The problem is that the frame has slided to an offset position thus giving me a border on the top and lefthand side while obliterating part of the selection, secondly, taking no account of previous tonal adjustment.
To explain the process: I am working on scanned hundred years old stereo photos - some polychromatics - to transform them into printable anaglyphs.
I manage the up coming issue but I think it is more like a bug and wanted to report it as it occurs from time to time on long sessions. It doesn't occur on the same work when I cancell operations down to adjustments and process again?!

OK. I can see that it's offset in the screenshots you provided - but I'm still a bit unclear on how you got there. It sounds like this doesn't happen consistently. Is it possible to create a screen capture(video) of your process so that we might be able to better understand and follow your process - and hopefully see how to reproduce the issue you are seeing?

(Oups! I answered in the wrong window)
I'll try to make that video, expected the issue arrives soon! but already I can describe the steps as they come:
1. open a scan of 4 b/w glass supported stereo photos (600 dpi)
2. change colour mode b/w -> RGB
3. select and copy one of the 4
4. create new entry and paste it (layer 1)
5. adjust tone using different parameters
6. select and cut the left image (smaller than half image as there is a frame all around)
7. select the right image and reframe (still layer 1), sometimes the frame stays selected
8. go to level adjustment
9. Choose red and change out value from 255 to 2 (cyan) - ok
10. deselect if necessary
11. paste (layer 2)
This is where the problem sometimes occurs
When going back (cmd+Z) to step 5 and process again all is ok

Since last comment, I processed 12 images. The problem occurred once. I followed the same paths as described but as for some other images coming afterwards I did a zoom in, used the stamp and zoomed out between steps 4 and 5 but all went right!
Have a good day.
