i don't know why you were doing the kernel/vga driver update, but if there wasn't a particular bug you were fixing, i would downgrade the kernel/driver/X server back to previous, working versions..

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.
