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.
