Public bug reported:
I have recently noticed that when setting sRGB images as the desktop
image, and having the desktop icons active (gsettings set
org.gnome.desktop.background show-desktop-icons true) that there is a
strange dimming affect, so I turn my machine on, log on, and then I see
my image normally for a few seconds, then suddenly it is dimmed and
stays like that, there are only a few seconds on login that I can then
see it normally for.
But I find that if I set desktop icons to inactive (gsettings set
org.gnome.desktop.background show-desktop-icons false) that the problem
goes away until I reactivate them, in which case the immediate moment
that I turn them back on in the settings the desktop image dims.
However this does not occur with just normal RGB or PNG images.
