[kde-linux] okular weirdness

[paul s]

for a couple of months now i have lived with some weirdness in okular...
i have removed:

~/.kde/share/apps/okular
~/.kde/share/config/okular*

uninstalled and re-installed most components and dependencies, created
fresh accounts, yet to no avail am unable to solve this issue...

on this computer my pdf's look as so...

http://queuemail.com/snapshot8.png

and on two other identically configured computers the same pdf looks
normal...

all are running
Linux 2.6.29.6-217.2.8.fc11.x86_64 #1 SMP Sat Aug 15 01:06:26 EDT 2009
x86_64 x86_64 x86_64 GNU/Linux

and libraries from these repos...

i am not running selinux and the only thing i can think of is the video
card...

C0: radeon driver(snapshot)
C1: nv driver
C2: radeon driver

any thoughts or alternate ways of thinking would be appreciated.

cheers
