[gfx.color_management.enablev4] Wrong colors in some images in Firefox (reminds of negative)
Last modified: 2016-12-20 10:49:39 EST
Description of problem:
Firefox shows incorrect colors on specific images. The image looks like a negative. I've only seen this on images on http://www.nrc.nl .Other browers show colors correctly.
I've uploaded a screenshot which shows this clearly:
The screenshot shows the same image in FF, Chrome, eog and epiphany.
The actual image:
Firefox on Ubuntu does not show this problem.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Open provided link
I can reproduce. Peter, can you please look at it?
When I set gfx.color_management.mode to 0 it shows the colors correctly. The default is 2.
I've checked on the ubuntu system and it also has the setting set to 2, but there it does show the image colors correctly.
The colors now look different, but still not correct.
Same version of firefox, I'm trying to check which update might have caused this.
ff43 still affected
Seems to be caused by some Fedora Firefox settings, may be caused by image library we use in Fedora. If I built Fedora Firefox with default settings (default mean Mozilla default) the image is show correctly.
it's caused by gfx.color_management.enablev4 which is enabled in Fedora.
Tested in FF44 on F23 and can confirm that changing the gfx.color_management.enablev4 setting to false shows the image how it is intended to be.
Could the default be changed?
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining

version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's

more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
