I re-flashed my mako today and tested it again and can reproduce the issue every time I test it. Perhaps you didn't have the display forced on (as described below).
How to reproduce: 1. Force the phone not to suspend: powerd-cli display on bright & 2. Start calendar app and find the pid: ps -ef | grep calendar.qml 3.
