Hi,
I attached to this message a patch to fix the overflow when fullqueries is activated and full queries are taking more than a line that might be resulting in a page overflow (the informations shown on mytop will exceed the terminal height).
As for the latest commit upstream (21, mar 2013 https://github.com/jzawodn/mytop/commit/437f2ef8d3fce02eafe935ddbf860d1dfbc43f7d) its only a small fix that seems to already have been fixed on the MariaDB version.
Regards.
