Are you able to post the images? I think the group doesn't allow 
pictures but you can try or upload some place and link it.

cairo_set_source_rgb(cr, 0.7, 0.3, 0.2);
cairo_set_operator (cr, CAIRO_OPERATOR_SOURCE);
cairo_paint(cr);

In short, this code sets the colour to rgb(0.7, 0.3, 0.3) and then seems 
to paint the whole surface in that colour. So, if you did:
- paint the whole surface in a colour
- draw the text for player 1
- paint the whole surface in a colour [again]
- draw the text for player 2

But if you have removed it and you're still not seeing both texts, 
something else is going on.

Best Regards,
Mohit.
