           Summary: Evince is very slow showing pages of some PDFs which
                    contain only images
           Product: poppler
           Version: unspecified
          Platform: x86 (IA32)
               URL: http://www.dccomics.com/media/excerpts/1696_1.pdf
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: cairo backend
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: matteo-ml at member.fsf.org


I did open gnome bug 577093, but the problem is reportedly with poppler (here
I'm using version 0.10.4).

Please describe the problem:
For some PDFs, evince 2.26.0 is veeery slow showing pages.
Take for example: http://www.dccomics.com/media/excerpts/1696_1.pdf

On my >700Mb RAM, 2.4Ghz Intel P4, each page takes 20-30 seconds to load.
Adobe Acrobat Reader does show the pages almost instantly.

Steps to reproduce:
1. Download the PDF
2. Open it in evince
3. Enable "continuous mode" to see better in how much time pages are loaded
4. Wait, scrolling the document down as the pages are rendered.

Actual results:
Each page is rendered after a lot of waiting.

Expected results:
Rendering of each page in under 3-4 seconds.

Does this happen every time?
Oh, yes.
