Public bug reported:
Steps to reproduce:
1./ Installed ICC color profile in Ubuntu 24.04 under default Wayland session
2./ Configured Firefox to actually manage colors, because step above is not
enough
-Openned default Firefox Snap browser and go to about:config from URL bar
-Specified path to my ICC color profile in key
"gfx.color_management.display_profile"
-Changed key "gfx.color_management.mode" to "1"
Results:
After FF restart, colors are still the same, oversaturaded, unmanaged under
Wayland session.
However, under X11 session it's working as expected what i cannot explain..
(Maybe in X11 is whole UI, entire desktop enviroment fully color managed? I
don't know.)
Expected results under Wayland:
Color management should be workind in Wayland session the same way how
it's working with standard Firefox debian package.
It seems like it's related to snapd sanboxing, not giving FF access to
/home/usename/.local/share/icc/
ICC profile copied to my /home/username/ and specified in FF settings - this
way it works properly but this is only workaround. Other color managed snap
applications may have the same problem, making them unusable for serious work
where are accurate colors needed..
PS: I have also openned Bugzilla:
https://bugzilla.mozilla.org/show_bug.cgi?id=1961468
Maybe Ubuntu Security Center could work around this and ask user for
permission to read ICC profile (or custom font config, btw. this is also
not working). If could just specify custom location for FF to give
reading access, problem solved.
