I had the same bug on my Inspiron 1525 laptop with an Intel GM965/GL960 card.
I am suspicious that this is due to the Virtual screen size in the graphics card being set to 8192x8192
Previously I have always set this to a maximum of 2048x2048 or less in xorg.conf, to prevent running out of memory on the card and getting corruption.
However these settings seem to be ignored on Karmic; with the following configuration:
Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Virtual    2048 2048
        EndSubSection
EndSection

I still get this:

davidf@golg:~$ xrandr
Screen 0: minimum 320 x 200, current 3200 x 1080, maximum 8192 x 8192

(Note that my boot up resolution is smaller, at 1280x800, so that's not
what's adjusting the maximum)
