opengl performance issues and rendering bugs with a GeForce 8600M GT

[Giuseppe D'Angelo]

With an NVidia GeForce 8600M GT I'm experiencing huge performance issues with every opengl program.

- Compiz effects are terribly slowly and they move jerkly
- Some opengl app is completely broken, for instance meshlab ( http://meshlab.sourceforge.net/ ) or the QtOpenGL module: building and running the example here http://labs.trolltech.com/blogs/2008/06/27/accelerate-your-widgets-with-opengl/ gives the attached result instead of http://labs.trolltech.com/blogs/wp-content/uploads/2008/06/openglwidgets2.png .

With a GeForce 6600 everything's "fine".

Can you enable the hardy-proposed and hardy-updates repositories, install EnvyNG so as to install the latest release of the driver?

[Giuseppe D'Angelo (dangelo)]

Just did it. I installed the latest nvidia drivers with the envyng-gtk interface, but the issues are still the same.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
