ibus-daemon & gnome-shell: high cpu usage...

[Georgios Petasis]

Hi all,

Gnome (for some reason) takes all my cpu power under fedora 20 64 bit.
And if I kill ibus-deamon, the session still runs. But I cannot kill 
gnome-shell.

When ever I start a computation, gnome-shell kicks in, and takes *all* 
cpu. For example, when running (a single threaded) Tcl/Tk program:

Tasks: 291 total,   3 running, 288 sleeping,   0 stopped,   0 zombie
%Cpu(s): 52.0 us,  1.7 sy,  0.0 ni, 45.9 id,  0.1 wa,  0.1 hi,  0.0 si,  
0.0 st

My application shows a load of 93% (one of the cores), Xvnc 23% (the 
wish application updates some dialogs),
but gnome-shell eats 300% of my cpu (3 whole cores?). Is this normal?
I think it is very high...

George
