ADDITIONAL INFORMATION
Comment 1 Alex6 2024-05-23 08:10:32 UTC
Correct colors with perceptual gamma, incorrect with linear light. (no difference within Gimp)
Comment 2 Mirco Miranda 2024-12-24 18:56:35 UTC
Please attach test case images (jpg and xcf). It's likely the kimage-formats xcf plugin.

This was a problem with xcf from Gimp 2.x and linear light images.
But now with xcf Gimp 3.0 nothing works...
