Comment 2 for bug 1162008

I've just upgraded to Raring and noticed that the problem appears to be even worse now. It happens whenever I try to close or minimise Thunderbird. If I go to the ibus keyboard icon in the system tray and click on it, the drop down menu is in a state of constant flickering.

I did some experiments and noticed that killing the usr/share/ibus/ui/gtk/main.py python script process doesn't help. Thunderbird keeps using 100% cpu. Also, taking it one step further and killing the ibus process also doesn't help. Thunderbird keeps using 100% cpu.

I conclude from this that ibus is probably not the root cause of this problem. It's probably a Thunderbird/compiz incompatibility that is somehow causing ibus to refresh itself continuously.
