Screen flickers when typing

[cantab]

Strange problem now that I have upgraded to Intrepid. When I type, I get horizontal black lines flickering in random locations on my screen. How do I fix this?

I've ruled out physical vibration causing the problem (by holding my keyboard off my desk and typing).

I'm currently using the nv drivers.

Have you tried disabling the RANDR service?

System settings -> Advanced -> Service manager

Makes no difference.

I've also tried changing the resolution and the refresh rate, again to no avail.

I've encountered the same problem.
To the OP: If you've solved this, please write how you did that.
Any other ideas besides RANDR, which didn't work for me either?

Thanks
