Thanks for the link Alan, it's very useful. Actually this bug has been reported at that forum: http://www.google.com/cse?cx=partner-pub-6344472472167039%3Ayq78am-jukz&ie=ISO-8859-1&q=backingstore&sa=Search+Site I was having a similar crash with gnome/metacity when I upgraded to gnome 2.26 but I never tried to track down the bug, I just switched to openbox, which didn't crash in gnome. But in KDE/Openbox the crash happens, but less frequently than with KWin 2009/9/10 Frank Steinmetzger <war...@gmx.de>: > Am Donnerstag, 10.

One thing to notice is that BackingStore is implemented by de X server, not by the driver, So maybe this isn't a bug in nvidia-drivers IMHO you should use KDE4 as now it's pretty stable (without BackingStore, no issues at all here)
