Ubuntu :: 10.10 Theme - Text Blotted Out In OpenOffice Applications

I have been using Ubuntu 10.10 for a few months now. I enjoy working with it, but there is one strange problem with Open Office (and Inkscape as well). When I attempt to work with either the word processor or spread sheet (this probably applies to other Open Office applications as well) under the default theme in Ubuntu, inevitably I get text and other elements blotted out with line smudges.

I have included a couple of screen shots, but I am wondering if this is a recurring problem with theme support (Open Office doesn't really use GTK/Gnome, does it?) or if it is some strange affect with the nvidia driver that I installed (version 260-19-06, my card is a GeForce Go 7150M). I have also noticed a slightly different problem, with Inkscape, where the ruler marks that track. The cursor movement don't delete themselves when the cursor moves, so the little triangles build up.
