Seems to be cairo backend specific

> Seems to be cairo backend specific

I can't reproduce it, I see the same output than splash, which is different than the acroread screenshot (the background color).

Comment 4 Albert Astals Cid 2011-02-26 04:44:00 UTC

I do get an empty white background with cairo and a purple-ish one (yes a bit different from Acroread it seems with splash)

Ask anything you might want me to do to help see why i get nothing in cairo.

Comment 5 Carlos Garcia Campos 2011-02-26 05:16:17 UTC

Maybe it depends on pixman/cairo versions, I'm currently using git master for both.

Comment 6 Albert Astals Cid 2011-02-26 07:04:19 UTC

I'm using 
  pixman 0.20.2
  cairo 1.10.2
that i think are the latest versions. If you are sure this is a pixmap/cairo problem and not ours you should mark the bug as resolved->notourbug

Comment 7 Carlos Garcia Campos 2011-02-26 07:07:10 UTC

No, I'm not sure.

Comment 8 Germán Poo-Caamaño 2012-11-02 23:18:19 UTC

Before building cairo 1.12, I could reproduce this bug (with a white
background)  After building poppler on cairo 1.12, the PDF looks fine
to me.

Probably an issue with an old cairo version.

Comment 9 Albert Astals Cid 2012-11-19 21:20:44 UTC

So should we close this one?

Comment 10 Adrian Johnson 2012-11-20 10:52:15 UTC

Works for me with cairo 1.12. Looks like a cairo bug that has been fixed.
