Changes via “gsettings set” for GNOME animations have to be restored after every boot (and require toggling between values) on Ubuntu 20.04

I’m turning GNOME animations off via the following command in the terminal:

gsettings set "org.gnome.desktop.interface" "enable-animations" "false"

This works the very first time. After that, after every fresh boot, the effect is gone. I have to repeat changing the setting. And that’s not even enough:

Just repeating the same command is not sufficient. I first have to invert the setting, then put in the setting that I actually want again:

gsettings set "org.gnome.desktop.interface" "enable-animations" "true"
gsettings set "org.gnome.desktop.interface" "enable-animations" "false"

The above is what I need after every boot. Why is that?

How I see the results? In the “gedit” text editor, smooth scrolling depends on animations being enabled.

Edit 1: Where can I see the (lack of) effect from this option after a reboot? In gedit (long text document) and Nautilus (longer list of folders and files in default view), smooth scrolling is disabled immediately after setting the option, but is enabled again after a reboot. On the contrary, in the “Applications” list opened from the dock, the open/close animation for the list remains disabled after a reboot, and smooth scrolling in the list remains disabled as well.
