I am getting intermittent corruption on one of my monitors using
XScreenSaver.

I am running a fully updated Ubuntu 11.10 (64bit) installation on a dual
core AMD proc

The NVidia settings too reports that I am using driver #280.13 and XScerver Version 1.10.4, and I am using an older NVideo card:
  *-display               
       description: VGA compatible controller
       product: G73 [GeForce 7600 GT]
       vendor: nVidia Corporation
       physical id: 0
       bus info: pci@0000:01:00.0
       version: a1
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress vga_controller bus_master cap_list rom
       configuration: driver=nvidia latency=0
       resources: irq:18 memory:fa000000-faffffff memory:d0000000-dfffffff memory:fb000000-fbffffff ioport:ef00(size=128) memory:fc000000-fc01ffff

Corruption can occur on either one of the monitors, but I have not yet
seen it in both at the same time.  Once corruption occurs, XScreenSaver
does not recover the monitor.

I have not been able to totally isolate the conditions, but it seems to
occur more often if one of the monitors is displaying a maximized
window.

What other info might be helpful?
