   I've just posted truss logs for some of the applications at:

http://people.freebsd.org/~lioux/xorg/kpersonalizer-truss.log
http://people.freebsd.org/~lioux/xorg/kwin-truss.log
http://people.freebsd.org/~lioux/xorg/opera-truss.log

   Let me know if there is any further information I can provide.

   Regards,
