When you use "<" and ">" buttons on Month view to navigate calendar, Google Calendar events are duplicating each time you press the button (so if you do it 4 times you will end up with 5 copies of the same event displayed etc).
There was a similar issue for 7.x, but only when AJAX was disabled. Since, to my knowledge, AJAX isn't supported in 6.x, enabling this option does not resolve the issue.

+1 on this issue. I've spent a few hours poking around to find a solution, but haven't come up with a winner, yet.

Attach file contains an invasive fix module .. this module is primarily intended to fix Google Calendar events duplicating
https://www.drupal.org/node/1677632 ; it does an override on theme registry on every
views fullcalendar is responsible with via (jbsd_fullcalendar_theme_registry_alter)
and replaces contrib fullcalendar with jbsd_fullcalendar

See INSTALL.txt for install details. pretty much just enable module and clear all cache.

The culprit is how fullcalendar.library.js and fullcalendar.fullcalendar.js populates events.. might take a while to create a contrib patch for it or possibly instead of using v1.4.9 fullcalendar.js have to make use of v2.0.0 to make use of removeSources but then again.. bah .. creating contrib patch gonna take a while..
Which I am gonna have to pass. Enjoy the workaround fix.

Also here are my notes about trying to patch fix.

events is just about initialLoad afterwards eventSources are propagating.
