[cairo] Linux Windows differences (text)

[Luca Bacci]

Can you test if calling cairo_font_options_set_antialias (cr,
CAIRO_ANTIALIAS_NONE) has any observable effect on Linux?

If not, I think you can open an issue in
https://gitlab.freedesktop.org/cairo/cairo/-/issues - unless someone more
knowledgeable than me steps in :)

Regards,
Luca
