“Allow different input sources per window” is broken in Ubuntu 14.10 gnome-session-fallback and Compiz

[relgames]

I installed Ubuntu 14.10 and then installed gnome-session-fallback. Then I configured 2 input sources and enabled "Allow different input sources per window".

It works fine in Metacity but in Compiz layout is changed globally, completelly ignoring "different sources for each window" setting.
