Stephen, et al,

I'm not certain whether the cause of similar behavior is the same but the symptoms are very similar--especially the " when I move a window on the screen, the content isn't erased from the old location, leaving a trail of ghosts behind". In my case the ghosts do get erased after several seconds.

My setup is also quite different. I'm using X2go from a Dell Optiplex 9010 running Windows 7 to reach SL7 running on an HP DL360 in the basement. Initially, response was snappy and I had no problems loading up gobs of Firefox windows. Then, about two weeks ago--seems like years--response became less than acceptable. In my case response seems to get worse as the time since reboot on the Dell increases and a reboot provides temporary improvement.

Unfortunately, I've been sufficiently busy I haven't had time to chase down the cause of the changed behavior.

I have a Dell Optiplex 980 with a Radeon HD 6450 card which was working fine with the elrepo fglrx-x11-drv and kmod-fglrx packages until I recently upgraded to kernel 2.6.32-573.12.1.el6.x86_64 and fglrx versions 15.12-1. Now when I move a window on the screen, the content isn't erased from the old location, leaving a trail of ghosts behind. This happens with more than one window manager (fvwm, icewm, fluxbox), so I think its an X problem, rather than a window manager bug.

The guys at elrepo were very responsive, but they didn't have the problem on their own machines, and it's not really their software - it is closed source from ATI - and they have run out of guesses for what to try. I have tried installing ATI's own rpm and that behaves the same way. I've filed a bug on the unofficial ATI bugzilla, but don't have great hopes there. I'm wondering whether anyone here has ever seen symptoms like these. Using the radeon driver gets me a mostly usable system, but there is some stuff that says it won't work without glx.
