I am having the same problem with Fedora 9 + latest updates, no Fedora 10 involved. In addition to the problems described above, I get stray lines all over the screen.

Description of problem:
After using KDE4 with XRender desktop effects for several hours,
X rendering operations suddenly start slowing down, which quickly
proceeds to a complete X freeze. The rest of the system remains
operative, so it is possible to reboot it either remotely, or
through the ATX power button.
Version-Release number of selected component (if applicable):
Fedora 9 upgraded to Fedora 10 + latest updates.
Updating to kernel-22.214.171.124-123.fc10.i686
and xorg-x11-drv-ati-6.9.0-58.fc10.i386 did not have any effect.
Once or twice a day.
Attaching a debugger shows that X actually continues working,
but some ioctls hang in drm_fence_object_wait for minutes.
I'll try running with nomodeset, and without xorg.conf next.
I have no idea, what's this, but I have no F9 for testing anymore.
