Hi!
I just installed Centos 4.4 on a machine at work, yesterday. Mostly it went well with just a couple of glitches.
One of them is slow video performance. No, I'm not playing 3d games at work! :)
Scrolling/repainting terminal windows is plainly MUCH slower than it is on my Centos 4.4 desktop at home. Machine at home is an Athlon XP 2600+ with one gig of RAM. Machine at work is a P4 2.26 Ghz with a gig of RAM.
Before Centos, the one at work had RHEL WS 2.1, which did not exhibit the same issue. It was using KDE as the main desktop, while this time it is (so far) set to use Gnome (as is the box at home).
Scrolling through a big file with less, for example, you can watch it paint the screen. Hitting 'B' to go back a screen is almost painful, you see it scroll part of the screen down, slowly, then fill in each line above that.
It's the same hardware that was there before, the only thing that has changed is the OS.
Clues?
Thanks!

Nope. But see here for confirmation, at least.

It happens on my 1.8GHz Athlon (PR2200+) with a Radeon AGP at 4X, 128MB aperture too. I didn't post that one though.

BTW. With a Radeon card, like mine, default for DRI is off. But I've been running DRI enabled successfully on both the old machine and the Athlon for over a year w/NP.
So I enabled it again on the Athlon and did see some improvement (confirmation: glxgears went from abysmal appx. 140 fps back up to 68fps, appx.).
If you previously had DRI enabled, it *may* have been disabled. Did you run update and then locate rpmsave and/or rpmupdate?

No, I blew it away and did a fresh install on the machine that's slow. On my system at home it was an upgrade from a previous installation, and it doesn't exhibit the problem.
