Description Hoang Duy Tran 2021-11-11 17:23:47 UTC 
SUMMARY
Tried to make a backup layer, as a background, with lock to avoid editing, and when convert the NON-LOCKING layer, the entire layer stack is OVERRIDEN with a new arrangement, remove my backup and using my backup layer as the selection mask

STEPS TO REPRODUCE
1. Load an image as a background
2. Make a backup by cloning background, lock the backup at the bottom, make it invisible
3. Move to the clone, right click, select 'Convert -> Convert to Selection Mask'

OBSERVED RESULT
Cloned layer has been removed (where is it????) and my backup background, locked, is now made the invisible, transparent, where is my original backup layer?

EXPECTED RESULT
Perform conversion only on the layer I was on, leaving my backup/invisible/locked layer alone as it was

SOFTWARE/OS VERSIONS
macOS: Catalina 10.15.7

Note: You didn't clone the Backround layer, you Duplicated it.
When you convert a layer to a selection mask, it's converted to a mask and applied to the layer below, as a selection mask.

So, it was applied to the original Background layer that you'd made invisible and locked.
Comment 2 Hoang Duy Tran 2021-11-11 19:40:13 UTC 
I just redo it with 'CLONING' and the result is identical
Comment 3 Ahab Greybeard 2021-11-11 19:55:33 UTC 
Yes, the Clone layer is converted to a selection mask and applied to the original Background layer.
This does not alter the contents of the Background layer.
Comment 4 Hoang Duy Tran 2021-11-13 02:49:29 UTC 
No it doesn't. The result is identical to the one taken with a copying of layer. The layer I'm asking the software to work on is the COPY/CLONE of the original, I'm NOT asking it to work on the original or expecting it to REMOVE my COPY/CLONE layer and use the ORIGINAL image in the operation.

I would suggest that any further discussion of this subject be done as a new topic in https://krita-artists.org/ with a reference link to this bug report.

Resolving: this is intended behaviour.
