If you enable the client console (Help → Diagnostics, or Ctrl + Shift + F7) you should see a message with some indication of what triggered the client update; something like:
11:39:50.330 [AWT-EventQueue-2] INFO com.inductiveautomation.factorypmi.application.runtime.ClientPanel - Received project change notification: notificationMode=PUSH, updateMessage=ProjectUpdated(editCount=3085, uuid=561196fa-5d3e-bcad-a216-567792d2aa89)
If you then go to the gateway webpage, then Configure → System → Projects, choose ‘Details’ on your project, you should see edit number from the client update reflected.
If you’re seeing global resources/the ‘global’ project as the source of the changes, then you might have some other user triggering changes by saving a global resource on another designer session. There is a minor issue regarding scoping of these global changes that’s still currently active.
