gnome-calendar runs in background and uses a lot of memory

[Balazs Pere]

Some minutes after I logged in I realized that gnome-calendar runs in the background and uses more than 400MB memory. I don't launched it. Is it normal?

This is still a problem in Ubuntu 20.04.

I am also noticing high CPU usage and UI often triggers "this app is frozen, kill it?" message.
