This is not a new problem, it happens since I can recall in a default
virt-manager qemu-kvm VM using qxl video. It's easy to reproduce in VM
as well as baremetal.
See screenshot here:

The questions are: is it expected these processes take up this much
CPU? is there low hanging fruit here? Even cutting it in half would be
huge. How to profile and file a bug against these likely separate
problems?
Maybe it's worth in the next cycle trying zstd for squashfs.img
compression in lieu of xz. That might be related to loop1 taking such
a big hit, but I don't know for sure that loop1 rather than loop0 is
really the process taking the xz decompression hit.

Hi,
maybe, in case of gnome-shell, it's related to the GtkSpinner there?

And if your VM works the same as mine rawhide VM, then you should not
move the mouse cursor left-right-left-right-... quickly, neither in
gdm, because it causes significant CPU usage as well, even when moving
the mouse above the gray area in gdm, where is nothing to be clicked.
Just mine semi-recent experience.

Yeah, that was my initial thought too. We've definitely discussed that
spinner wrt CPU usage in anaconda before.

I don't think gnome-shell eating this much CPU can be solely caused by a
GTK+ bug - even if GTK+ is redrawing the entire window constantly, that
cannot cause 40x more CPU to be used in gnome-shell than in anaconda unless
something else is going on.

Tried this suggestion in the bug:
create /etc/gtk-3.0/settings.ini with this contents:
[Settings]
gtk-enable-animations=0
No change.
