I believe this latter is the Xorg provided since I'm trying hard to just be a user since I exited the biz many years ago when I kept up with everything.
The /var/log/Xorg.0.log shows, among other things...

The next thing I'd do is boot the last kernel under which you saw "normal" performance. If booting the older kernel doesn't fix the problem, then the problem is probably the X11 server. At that point, I'd start using "yum downgrade" to revert individual components, and reboot until you find the change that fixes performance. xorg-x11-server-Xorg and xorg-x11-drv-<something> are the ones I'd check first.
There was a time I had the time, interest and expertise to do all that. I actually thought it was fun and worthwhile.
I've successfully transitioned to a TDU (Typical Dump User) now though and try to limit how much of my resources I devote to debugging issues caused by ... Well never mind as a list of pejorative terms related to how things are done these days seems inappropriate considering the development model used.
But I do thank you for both the suggestions and taking the time to help me get this far along. Tonight I may see some benefit from the disabling of java in libreoffice, and if so that will have been a very big help.
The Ksnapshot lagging and jerky region selection won't be as big an issue as it would have been six months or further back when I had to occasionally select very quickly very large regions on a "largeish" hi-res display when stuff was flying by very, very quickly.
My only next project is to get the new upstart .override working right to try and start gdm and gdm-binary on tty7 instead of tty1 so that telinit will work the way "God" intended instead of they way it doesn't now.
Last time I tried the .override I apparently didn't get it right as it didn't work. But I had read slap-dash and only partially so I know I should be able to get better results with a little more care.
