Default Re: Nvidia 9600GT: Xorg process and high CPU usage

This happened to be bigger, but is a file a little over 1Mbyte, so hardly large.

I closed all okular processes and this had no effect on xorg memory use. It is still 606m.

Does this help?
Is there anything else I can look at to help diagnose this?
OK, I've been running for a few days now without running okular (using foxit reader instead).
And memory use (and so performance) have been just fine.
Memory use by Xorg has not wavered by more than a few Mbytes - whereas previously it jumped by 100's MBytes!

So I don't know whether it is okular per se that is defective, or whether okular simply uses some xorg/nvidea call/feature that exposes the defect.
Anyway, using foxit reader instead of okular has made my desktop usable and reliable once again!
This only appears ok statistically, but so far so good. I shall post every week or so to reconfirm. If I have time, I'll start using okular again to recheck that that still fails.
