NixOS: Webpages do not render.

[alcinnz]

While the pages do appear to be receiving input events and notifying Odysseus of any links being hovered over, nothing is being rendered to screen.

Some packages that might be useful to look at:

And this issue looks relevant: NixOS/nixpkgs#32580

Hi I maintain Pantheon in NixOS.

We had a similar problem with ephemeral NixOS/nixpkgs#61665 (comment)
This was fixed by adding glib-networking to buildInputs.
It needs glib-networking in GIO_EXTRA_MODULES to work.
