Do you mean that your red drawing hack shows non-Render solid fills,
but not Render-based solid fills?

What evidence do you have that GTK+ probably isn't drawing through
Render?

From its beginning, cairo has always preferred to draw things with
Render whenever possible, so since GTK+ started drawing with cairo it
definitely should be drawing as much as possible with cairo.

With a GTK+/cairo stack things like solid fills should be going
through Render and should be hitting accelerated paths for that. If
not, then there are performance bugs that I would be very interested
in hearing more details about so that we can fix them.
