wobbly windows snatching doesn't work properly

Hi;

I am on Ubuntu 14.04 32 bit platform, I have Compiz 0.9.11.2. I enabled wobbly windows effect, it works well except snatching effect. When a window is fullscreen and if I pull it from its title bar and drag it towards center of the screen, it won't split off properly , it won't lose fullscreen mode, it resides in the center of screen as if it's fullscreen. It doesn't happen always. I can produce bug in chromium 36
I hope you fix it or help me fix it.
Thanks.
Kenn
