If I'm reading this right, looks like cairo gi bindings are handwritten, and very incomplete to my eyes: https://github.com/GNOME/gobject-introspection/blob/main/gir/cairo-1.0.gir.in Eg. the simplest function, `cairo_image_surface_create()` has no parameters annotated: ```     ```...

> Sounds similar to this issue https://gitlab.gnome.org/GNOME/pygobject/-/issues/16, so likely a pygobject issue. However, CairoFontFace does have a record in: https://github.com/GNOME/gobject-introspection/blob/main/gir/cairo-1.0.gir.in Same error when you search, other people (mostly on Ubuntu)...

I see. Thanks. Okay, I'm binding font-face and scaled-font now.
