metacity grey background at session startup

[Lucazade]

when I load the unity-2d session there is a grey background between lightdm and the wallpaper.
to provide a flickerless experience I believe this background should be black and not grey.

it is due to the xrender compositor of metacity.. attached there is a patch to fix this glitch.

I can confirm the patch really works.
Not that I had tested it with Unity-2d.
But I have tested in with the fallback session of Gnome-shell (Gnome-panel) and the annoying flickering is gone.
I use Nvidia graphics card and nvidia-current drivers.

is it possible to integrate this patch? it would be nice to have this solved for Precise.

Your patch doesn't solve the core problem unfortunately. Ideally, we should not draw anything until we have the background wallpaper loaded and ready. A black screen isn't a big improvement over a grey screen overall. I'd rather a better fix.

[Lucazade (lucazade)]

this for sure.. I'd like a proper fix but anyway a black screen instead of a broken grey is better than nothing :)
