797656 - Shifted hue tones / pink people

Status: NEW

(Core :: Graphics: Color Management, defect)

Description

Attachment: screenshot

A friend's computer, running Firefox 15.0.1 on Fedora 17 64-bits, on a Thinkpad X200s with Intel graphics and GNOME Shell, exhibits pinkish pictures tones.

The problem was primarily noticed on Facebook, and mostly for enlarged images (not the small square profile pictures in a conversation thread). However, using that computer, I was also able to see that, outside Facebook, some images are affected while others aren't, as the attached screenshot of lapresse.ca demonstrates.

Furthermore,
- I tested on a Thinkpad X220 running Fedora 17 32-bits with Intel Sandybridge graphics and was unable to reproduce the issue on my computer.
- Trying with a blank Firefox profile on the affected computer does not make the problem go away
- Webkit-based browsers (like Epiphany 3.4) are not affected
- Saving the relevant images to disk and viewing them with an image viewer does not exhibit the problem
- Taking a screenshot of the screen preserves, as you can see, the pink hue

This is one of the images that has normal colors on lapresse.ca

This is one of the images with a pink hue, saved from lapresse.ca alongside the unaffected sample image.

lspci output, though I doubt it will be of any help. Also note that it will be difficult for me to dig for further information unless my friend brings the computer back to me for maintenance.

This is very likely a problem with the color profile or graphic card driver on the system. Only images with an embedded color profile are affected.
Switch gfx.color_management.mode to 0 via about:config

For the record, I've now had the opportunity to test changing "gfx.color_management.mode" to 0, and I can confirm that this workaround makes the problem go away.

This doesn't seem to be limited to Linux.  There's some discussion of it on the Wikimedia bug tracker: https://bugzilla.wikimedia.org/show_bug.cgi?id=30249 https://bugzilla.wikimedia.org/show_bug.cgi?id=30214
