I have a corrupted Ambiance theme... the background of the top menus is grey :( i must have done some fiddling...
If i choose another theme, it seems to work fine, but I want Ambiance :D what do you think i could try?
I already tried downloading ambiance again, but same issue happens. I tried to download gnome color chooser, but it doesn't do nothing, so i guess maybe i can change something else... but where?
Here's a screenshot:
