Bug Description
The screen flickers upon session start (seems I get a filled rectangle for every element that's about to get drawn).
Attaching a clip of it happening in VirtualBox, but it also happens on two actual systems (Intel HD 2000 and 3000).

I investigated the issue a bit, and according to my findings this is not a bug in unity-2d: if I remove the unity-2d related names from the "RequiredProviders" line in the /usr/share/ gnome-session/ sessions/ ubuntu- 2d.session file, the flickering still happens.
I suspect that this bug might be related to metacity: in fact, if I don't start metacity, no flickering occurs; and if I manually start metacity from an xterm (with no other window manager running), then flickering occurs inside the xterm.
I'm reassigning this to metacity for investigation.
