Description Simon 2011-02-25 07:53:22 UTC 
Version:           0.10.5 (using KDE 4.5.5) 
OS:                Linux

Please check this PDF with Okular:
http://www.cvg.ethz.ch/teaching/2011spring/gpgpu/Lec1-intro.pdf
Here my CPU goes to 100% for several seconds just to display the first page. Same for the second page, etc.

Displaying the first page takes entire 2 seconds. Compared with epdfview: Less than 0.1 second (I guess) for displaying any page, CPU stays at about 0.

Reproducible: Always




OS: Linux (x86_64) release 2.6.37-0.slh.25-aptosid-amd64
