keyboard shortcuts misbehavior Gnome 3.6

Question

I've enabled few Keyboard-shortcuts and they work weird.

1. Shortcuts with Ctrl+Alt+
   

   I've enabled Ctrl+Alt+C to open a Google-chrome browser.
   Works only when I hold the Ctrl+Alt for a while.
   Works fine for default shortcuts like lock-screen (Ctrl+Alt+Delete) and gnome-terminal (Ctrl+Alt+T)

2. Shortcuts with Super+
   I've enabled "Super+F" to open a Google-chrome browser with facebook URL
   Works only if I press "F" twice without releasing the "Super" key

Can someone help me fixing the issue (or) Confirm this behavior/bug?

OS - Ubuntu 12.10
Gnome - 3.6 (PPA)

Answer 1

Try disabling the "Show location of pointer" using the Gnome Tweak Tool.
