This must be a bug in the graphics driver. xscreensaver just uses standard X11 requests to blank or turn off the screen. You may check if turning off the screen with DPMS causes the corruption. First stop the xscreensaver daemon:
 xscreensaver-command -exit
Then power down the screen and on again after 5 seconds:
 xset dpms force off; sleep 5; xset dpms force on
