GNOME Bugzilla – Bug 776888
color correction not working on Wayland

Created attachment 342921 [details] Sample Image Opening jpeg images with and embedded Adobe RGB profile when using wayland using eog shows incorrect colors. When opening the same image on xorg the correct colors are shown. In addition, setting the image as the desktop background image results in incorrect colors regardless of xorg or wayland being used.
That seems to be a missing part in eog's Wayland support right now. With X11 eog could query the display server for the display's ICC profile to do the color conversion. I am not sure right now if anything like that is possible on Wayland. But, normally eog has a fallback that assumes an sRGB display if it doesn't find a display profile. That seems to be broken too.
Okay, color correction appears to be kind of a heated topic on wayland-devel right now. So, let's wait what comes from that. But, if it's not working out in the foreseeable future we probably have to interface with colord to get the display profile. In the meantime I separated the sRGB fallback into bug 776984 as that can be fixed without a Wayland extension.
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new ticket at https://gitlab.gnome.org/GNOME/eog/-/issues/ Thank you for your understanding and your help.
