Confirming here on Kubuntu Intrepid 8.10 rc, nvidia 177.80 drivers. With "Backingstore" option set to on KDE4 crashes *a lot* - mostly using Konsole. If Konsole gets remembered in session, this leads to KDE4 crashing immediately after login.
@Chris: I think this bug may affect more people than expected; examples:
- http://www.nvnews.net/vbulletin/showthread.php?t=120630
- http://my.stargazer.at/2008/10/13/kde-4-no-thanks-yet/

Moreover, one can easily find instructions to improve performance in KDE4 for nVidia cards like this: http://userbase.kde.org/GPU-Performance and setting backingstore to "on" is mentioned all the time. It really took me a while to find this bug report and an advice: http://forum.kde.org/showthread.php?tid=6721&pid=7344#pid7344.
