This looks like out-of-range values in the resulting image.
The Despeckle filter has been made by @garagecoder , maybe he could help ?
from gmic-qt.

I'll try to reproduce the problem this week, then perhaps a fix

Thank you.
I had difficulty to find how to ask help for a specific plugin of gmic-qt!

@Antonio-52 So far, I've not been able to reproduce this. Are you able to provide an example input image which has the issue?
Mathematically, I can't see how that could happen unless there's something strange about the input first. If you have time, it would also be good to know if you see the issue with g'mic in some other program (e.g. gimp plugin, or standalone).

@Kelday
After some time I tested again the despeckle filter (with default parameters), but the problem still exists.
I work with Digikam 8.1 and cannot update to version 8.3 (OS problem).
I attached two images that have the pink problem.
- 1996-09-04 11h - Valle Ihlara; 235_v1.jpg :: FILE WORKED, WITH PINK TRACES
- 1996-09-04 11h - Valle Ihlara; 235_v2.jpg :: ORIGINAL FILE
Thank you!

Hi @Antonio-52
Unfortunately, I don't see your attached images on here or by email!
Maybe you can paste directly here in github rather than reply by email?
What I might need to do for you is create a new/test version of the despeckle filter. That way, I can add some features without breaking it for others. Hopefully I'll be able to do that this weekend.
Thanks for the feedback

Ok, I'll try to load images to GitHub.
Thanks!

@Antonio-52 I still can't reproduce this, even with those images. I think something is going wrong your side which is probably not due to this filter. I expect you could find other filters in g'mic which would break in similar ways.
I've added a new test filter called "Despeckle [test]" which has two clipping options. Both will stop any values outside 8bit range [0,255]. ClipIn clips before the filter is applied, ClipOut happens after.
If using ClipIn solves it, I think that shows something goes wrong before the filter. If just ClipOut solves it, then the filter is going wrong in a way I don't yet understand.
You will need a very recent version of g'mic to try that test filter!
