GNOME calendar with Graphic updates enabled

The main UI of gnome-calendar is redrawn unnecessarily. Even when the mouse movement happens on some other window, the gnome-calendar UI is updated for no reason.

For this reason, gnome-calendar really much CPU than it should.

The attached screencast is recorded using gtk inspector with Graphic updates shown.

Could you please confirm which version is your Calendar? I addressed a similar issue on Calendar 3.18.3 (https://git.gnome.org/browse/gnome-calendar/commit/?h=gnome-3-18&id=ee9bb968db9cf4f854c8c98bcdb7e360993e3fe4).

> Could you please confirm which version is your Calendar?

That was with GNOME calendar 3.18.2.1 which was on my probably not up to date Fedora 23 System. On GNOME calendar 3.20 it seems to be fixed.

Though there is a minor glitch in GNOME Calendar 3.20, where it redraws when mouse pointer moves from one week to another (in month view), say for example moving mouse pointer from July 8 to July 15 2016. 

There is also another minor glitch where the whole window is redrawn (and not just the dirty area) when clicking a cell (both in month and year view)

In current flatpak master, you can notice a delay when hovering the mouse over days in year view. This might be a result of this issue.
