I am on 12.04 and 3.4 gnome at the moment. I did a gnome update to 3.6 and downgraded back to 3.4 as it was not working. Now I have this annoying problem with gtk-themes. The default themes work properly (adwaita,ambiance, radiance), but all my custom themes are having menu color problems.
See picture below :
and some don't even show a menu, which is also not clickable. Any idea how to fix this problem? It also affects lightdm.
Thanks in advance
