+ The "New Message" box is very CPU intensive, to the point that when
typing a message, it takes a noticeable amount of time for characters to
register. This impacts the rest of the computing experience as the mouse
movements become jagged and the whole UI is less responsive than normal.
A quick check using System Monitor shows that when the "New Message" box
is open, whatever is running consumes more that a full core on an Intel
i5 processor (see attached screenshot).

Steps to reproduce:
1. Start the system monitor to keep an eye on performance,
2. Click the envelope in the panel and select Broadcast / Messages to open Gwibber,
3. Click on the "New Message" button,
4. The "New Message" entry box opens,
5. Start typing in the box.

Expected behaviour:
The new message box should allow the user to enter a message without any negative performance impact.

Actual behaviour:
When the new message box is open, CPU usage shoots up and stays very high irrespective of whether the user enters any data in the box. As a result, data entry is visibly jagged and so are mouse movements and anything else related to using the machine.
