Bug#642497: nvidia-glx: incorrect rendering followed by xserver infinite loop when using some OpenGL apps

[JS]

I've posted this issue along with an nvidia-bug-report.log.gz that caught the problem to the NVIDIA thread:    http://www.nvnews.net/vbulletin/showthread.php?t=167084

This worked correctly on my first install of Wheezy on 07/23 with the same linux kernel I'm currently using,  2.6.39-2-686-pae.
I'm working on installing from snapshot.debian.org all the packages providing shared libs to the OpenGL applications with this problem but haven't completed this.
thanks,--jack

In that case, probably some other change introduced in the Aug 17 update
caused these problems. /var/log/dpkg.log*, /var/log/term.log*,
/var/log/aptitude* should contain your upgrade history.

There is nothing we can do about these problems in the closed source
driver. Please report them directly to NVIDIA, following their bug
reporting instructions:

can't be, this should be completely unrelated

Have you tried creating a completely new user account (with no
accumulated cruft in his dot-files) and testing as this user?

Turning off desktop effects has also helped some users.

Another sign that this is not a packaging issue.

Xserver 1.11.0 is problematic, a fix has been submitted to upstream and
will be included in 1.11.1, but if you stayed with 1.10.x this should be
not your issue.

Have you tried a different kernel version/flavor?

If you report this to NVIDIA, please post the URL to the corresponding
forum thread to this Debian bug report, so that others may follow progress.
