            Bug ID: 91249
           Summary: Poppler extremely slow to render this PDF file [1]
           Product: poppler
           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: general
          Assignee: poppler-bugs at lists.freedesktop.org

Hello,

Certain PDFs opened in Evince or Atril using the Poppler backend are extremely
slow to render, to the point of being unusable. This is on a very fast Thinkpad
laptop with a quad-core processor and an SSD. The same PDFs render instantly
using a Windows PDF reader
(http://www.tracker-software.com/product/pdf-xchange-viewer) (running under
Wine!!).

This file is only about 2MB, but it takes many seconds to render each page:

On the other hand, some long, complex PDFs with images render quickly with
Poppler, like this one:

Thanks for looking into this.
