This bug seems nvidia closed driver bug.
So report to this : https://bugs.freedesktop.org/show_bug.cgi?id=6349
Perhaps, but this is not FC5. Closed driver is working fine on FC5, which
is based on 1.0.9. This happens if you update to FC6-devel from rawhide.
Thanks for the report. For users who are experiencing problems
installing, configuring, or using the unsupported 3rd party
proprietary "nvidia" video driver, Nvidia provides indirect
customer support via an online web based support forum. Nvidia
monitors these web forums for commonly reported problems and
passes them on to Nvidia engineers for investigation. Once
they've isolated a particular problem, it is often fixed in
a future video driver update.
The NVNews Nvidia Linux driver forum is located at:
Once you have reported this issue in the Nvidia web forums,
others who may have experienced the particular problem may
be able to assist. If there is a real bug occuring, Nvidia
will be able to determine this, and will likely resolve the
issue in a future driver update for the operating system
releases that they officially support.
While Red Hat does not support the proprietary nvidia driver,
users requiring technical support may also find the various
X.Org, XFree86, and Red Hat mailing lists helpful in finding

Setting status to "CANTFIX" (unsupported).
Even if it *is* an NVidia bug, something changed between
xorg-x11-server-Xorg-1.0.1-9.i386.rpm (which worked fine) and
xorg-x11-server-Xorg-184.108.40.206-1.i386.rpm (which demonstrates the problem).
I'll see if I can replicate it with the 'nv' driver.
Confirmed NVidia issue. Running 1.0.1-9, both 'nv' and 'nvidia' drivers work.
However, upgrading to 1.0.99-1 results in:
(II) LoadModule: "nv"
(II) Loading /usr/lib/xorg/modules/drivers/nv_drv.so
(II) Module nv: vendor="X.Org Foundation"
compiled for 7.0.0, module version = 1.0.1
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 0.8
(this driver works fine, although slow)
(II) LoadModule: "nvidia"
(II) Loading /usr/lib/xorg/modules/drivers/nvidia_drv.o
(II) Module nvidia: vendor="NVIDIA Corporation"
compiled for 4.0.2, module version = 1.0.8178
Module class: XFree86 Video Driver
(this one craps out with the symptoms described).
I'm guessing some API change between 1.0.1 and 1.0.99 that NVidia needs to

setting font antialiasing in gnome to subpixel smoothing fixed this for me.
another fix is to set "RenderAccel" to "false" in xorg.conf.
From Lars G :
Using your solution in comment #11 , this problem doesn't be fixed.
Following up with info from other bugzillas and similar....
NVidia has ack'ed that it's a driver problem on their part when used under the
most recent Xorg snapshots. There was an ABI change for the Glyphs code. They
intend to fix this in a future driver release. It's *not* fixed in the
just-released 8756 drivers.

Hopefully that information will be useful to Nvidia when they diagnose
the problem in their driver.
