Image appears too warmth when using some modules (ToneEQ or diffuse/sharpen or ....)

[atomikdg]

Describe the bug

I saw this bug when switching between local contrast and local contrast fast (diffuse/sharpen). This seems not related to a particular operation using module. I had it with color balance rgb on/off (when off, if I reset the module the yellow/warmth colors disappears). Also when zooming, the colors came back to normal.

If you need more information let me know.

Version: last 4.8.x ( 18026f9f50e97199a719627b0d61532e88aa4b23 ) but don't know when this bug came in.

Steps to reproduce

See videos here : https://nx22856.your-storageshare.de/s/aNgjDZSmcxNkzyo

Expected behavior

Image should be with "correct" colors

This is a not considered to be a bug I would say. You observe the effect of the very large filter radius.

If you want to avoid that You'd have to use the HQ button in darkroom.

Aah, I see now what you mean, seems to be a cache issue.

I can't reproduce here yet. Could you provide the image plus xmp, a log with '-d pipe' and the video while you reproduce the issue. That might help.

I guess you are sure your build is ok?

[atomikdg]

Yes my build is ok I tried with clang and gcc: same behavior Yesterday I have reproduced it (not with -d pipe). I'm trying today with -d pipe and give you the log

Another info: The warmth colors are exactly like when color calibration module is OFF

Ok, so i might have to check with images where there is a big difference between colors before / after color calibration.

I would also be good if you could check if the issue is happening with the temperature settings "camera reference" and / or "as shot to reference"

@jenshannoschwalm

On the previous nextcloud link (first post) you will find:

-The XMP + NEF files -Two new videos: bug_clang.mkv and bug_clang_expo/mkv -Two log files (-d pipe) relatives to the videos -A video with camera ref and as shot to ref --> I reproduced the bug with "camera reference". -A video when I activate or deactivate some modules

I can't reproduce it with gcc... but with clang 18.1.8 (I think I was wrong in my previous post but will try when I have some time).

[jenshannoschwalm]

It would be very / extremely important to know if this is a clang-only issue!
