disable_real_transparency doesn't work

Hi.
EDIT: It appears that it is now working, probabaly after rebooting. Sorry to bother you.
I am trying to use pseudo transparency. I have just installed Gnome Ubuntu 14.10 which uses Gnome Shell 3.12. Before, I had Ubuntu 14.04 on which I installed Gnome 3.10 from repositories. I was using lightdm.

I didn't do any changes to my config, but now I can see all windows trough, instead of my wallpaper. I would like to know, if this is perhaps a bug, or maybe I need to change something, somewhere?
Terminator version is 0.98 from repository, Gnome Shell version 3.12.2, using open radeon drivers. Here is my config:
