Transparency in this file incorrectly renders as opaque in evince

I created a simple pdf with alpha transparency and it looks fine in evince. However, I need to interact with adobe illustrator for work. When AI opens the pdf and saves it again, and then I load that pdf that was generated by AI in evince, then the transparency is broken. Everything looks opaque instead of transparent.

However, I can open the pdf that is generated by AI in Foxit Reader (on a computer running windows) and it looks fine. Another workaround is if I save from AI as PDF1.3 instead of PDF1.7 then it works, but I would rather not have to do this.

I am using Linux Mint 16 and the version of evince from the package manager (3.6.1 using cairo/poppler 0.24.1). I can provide more system details upon request.

I have attached the original file (transparency.pdf) which looks fine. And I have attached the file that is produced by AI (transparency_fromai.pdf) which looks wrong in evince.

I realize this is probably more of a bug in AI than it is in evince, but I would appreciate any suggestions for how I can open these PDF1.7 files in evince and view the transparency.

Hi Chris,

Thanks for the bug report.  It seems you have attached only one
document (transparency_fromai.pdf) of the two mentioned in your
comment.

I created this pdf file (in matplotlib) to contain transparency. It renders correctly in evince.

Thanks for taking the time to report this bug. This seems to be a bug
in poppler (the library used by evince to render PDF documents).
