It doesn't display in evince, displays perfectly with acroread.

I tried Evince in Leap and 13.1, acroread in 13.1.

Okular in 13.1 displays it, but at 100% CPU, a page at a time.

Ok, in fact, evince manages to display some pages after a minute of processing it at full cpu. I did not wait that long initially...

Acroread displays instantly at low cpu.

I tested the same PDF in 13.2 here.

Putting on my Scribus developers hat, welcome to the challenges of PDF display with open source tools.

Looking at the PDF with podofobrowser, shows this PDF has some 20000 objects inside.

It was created with Adobe InDesign for print. It's complex internally and has color managed high resolution images.

If a bug is reported against Scribus PDF's viewed in Evince it usually will be immediately closed with a comment about "get a real PDF viewer"

Okular, even using the same poppler backend does a *much* better job and what I see is as it brings a new page in the viewport it spikes the CPU for a short time and then goes back to idle.

Its not an openSUSE issue. Its an issue with poppler/libspectre and needs adressing there on freedektop.org

Acroread, even for Linux, is based on the same rendering engine used in all the Adobe proprietary apps and knows how to handle complex PDF in a way no other viewer can.

Maybe just a simple profiling would help to identify the cause? In anyway, as you suggested, this is an issue that should be solved in the upstream. Better to hunt for more performance optimization there. FWIW, I could display the PDF file with evince on my machine (on Leap), but it just took a few seconds to show up.
