Thread 106368995

GNOME's image viewer program, also known as eog will modify the image you are viewing when copying the image, in what I can only believe is some form of shady fingerprinting scheme.
Steps to replicate:
>Right click and copy pic related and paste it somewhere in your system (if using nautilus you can just paste it into some folder)
>Open the pasted image in "eog" - GNOME's image viewer
>Paste the image into the same folder
>Check pixel diff
For example for me, the pixel at X: 600 and Y: 250 is (216, 226, 236, 255) in original image and (215, 223, 235, 255) in image pasted from eog.
Pixel at X: 600 and Y: 250 is (16, 36, 61, 255) in original image and (25, 40, 61, 255) in image pasted from eog.

This shouldn't happen and it is a cause for concern.

usecase for privately duplicating images?

>>106368995 (OP)

is resampling for screenview feature no worries

>>106369063
I literally tried it with another program that also uses GdkPixbuf and it doesn't happen there. It is eog specific

>>106369091
What is even worse, this is not some size optimization because the image saved by eog is LARGER than the original, (800KB vs 1MB)

Try disabling resampling (image enhancement)

Bump

gnome glows

>>106368995 (OP)
not my problem

>>106368995 (OP)
Open an issue.

Why do you immediately jump to "muh malicious fingerprinting" instead of just assuming it's jeet code?

>>106369313
There is no such option in preferences
It keeps getting more and more suspicious.
Maybe it wasn't a deliberate decision by gnome but instead infiltration by a bad (state?) actor.
