So the update to Panopoly 1.14 switched panels layouts from the old Panopoly theme to Radix. But the Radix css isn't playing nice with Kalatheme and messes with fixed width. Read all about it here: https://www.drupal.org/node/2379315
Very easily fixable. There needs to be another container div in kalatheme's page.tpl.php in order for it to integrate seamlessly with the Radix layouts.
