It seems that the problem with this problem is open:
http://bugs.mysql.com/bug.php?id=72332
Open a SQL editor to a server and execute a query that returns some text fields, the columns don't autofit to a reasonable width to display as much as they can (or set in the Preferences as I believe 256 bytes..). Instead they are displayed in a super narrow table taking 1/20 of the screen width.
It seems to have changed from 6.1
Another way to expand the panel

Let me know in case you find it difficult.
