Seems to happen whenever multiple units start attacking structures.

looks like a graphic driver bug, could also be a badly written widget (would be a graphics oriented one).
so.. try using newer or older graphic drivers and switch off some widgets (though, i think it usually is the driver). maybe you can make it go away by reducing graphic settings too.
you are using 0.80.5.0, latest release is 0.80.5.2. am not sure, but i though there is an Ubuntu 9.10 repo that has this version.
