When running with Smarty 3 enabled on recent versions of Civicrm, the following notice is shown on my developer site:
Notice: Indirect modification of overloaded property CRM_Core_Smarty::$template_dir has no effect in _eventmessages_civix_civicrm_config() (line 107 of sites/default/files/civicrm/ext/de.systopia.eventmessages/eventmessages.civix.php).
Visiting an event page shows broken functionality. This is fixed if I revert to Smarty 2, but core is moving to Smarty 3 shortly.
