Hello, I tested your picture with XnviewMP 1.4.3 on Windows 10 64bit (latest updates) and could not detect any problems.

Maybe it is a problem of your operating system, graphic driver (old version) or something else!?

Thank you for the video. I read your older posts from 2022. You had some other color issues in the past with other jpeg files, too.
Maybe you can test the same situation again with a XnViewMP portable version, too.
It uses the standard settings and a fresh folder with all required files.

what do you have in Settings>View? And do you use ICC profile?

[spleen]

The issue remains whether or not an ICC profile was used.
Another interesting observation is that when I saved the JPG file to either a PNG or TIF format, the issue still existed.

Really strange, could you send me the png?

I tested the picture (med1) on different PCs.

incorrect: MSI (Intel i5-6400, NVIDIA GTX960)
incorrect: MSI (Intel i5-8400, NVIDIA GTX1050)
incorrect: MSI (Intel i7-10700, NVIDIA GTX1650S)
ok: ASUS (Intel i7-7500U, NVIDIA 940MX)

Weird enough, it's ok for med2.jpg for all PCs.

and if you use bilinear as resize method?

[spleen]

I tested the different zoom quality options:
bilinear, bicubic, spline16, spline36, lanczos3, lanczos4

bilinear: incorrect image at initial 100% viewing
the remaining 5 methods: initial 100% viewing ok -> incorrect after zoom in->zoom out /or/ after zoom out->zoom in

if you change 'pixel ratio' always the problem?

[spleen]

my default 'pixel ratio' is "D1/DV PAL (1.07)"
after I changed it to "square", wow, the issue is gone!

Ok, strange, i'll try to reproduce...
