[Bug 1391622] [NEW] Keyboard shortcuts unresponsive for several seconds

 

Public bug reported:

Sometimes global keyboard shortcuts like volume keys on multimedia
keyboard or Ctrl+Alt+T to open a new terminal, do not respond
immediately. They are buffered and respond after 15 seconds.

Started after I upgraded to 14.10
Occurs with Unity and Gnome Compiz.
Does not occur with normal Gnome and Xfce.

I can reproduce it with Kaffeine: just after I switch channel, all
shortcuts are unresponsive for 15 seconds.

I can sometimes reproduce it with Firefox: I play a HTML 5 video and
open a new tab or switch tab. Again all shortcuts are unresponsive for
15 seconds.
