Just noticed the link you provided includes a ref to spice-guest-tools.
With an Alpine client (and no "tools") I get less than optimal scaling from virt-manager - some black space at the horizontal edges, but there is a scaling of sorts going on, just not entirely using the available window space.
Are you using the stock version of virt-manager?
$ apt policy virt-manager
virt-manager:
Installed: 1:4.1.0-2
