Comment 7 for bug 296757

I will try to do some more testing once at home, as for compositing i don't use it with metacity so i should be in the same configuration than you.

I will check too in gDesklets options (gdesklets configure) if I've not enabled something i shouldn't.

I've searched everywhere users with similar issue and the only similar thing i've been able to find is the following ubuntuforums thread :

I'm scared to have an unusual issue.
