Ubuntu – Screen artifacts, particularly when scrolling through a webpage or document

When scrolling through a webpage or document, I get "artifacts", for lack of a better word. Part of the document will stay in the same spot and I wont be able to read what is under it. Since this is hard to describe, I've included two images to show what I mean. Although both of these are from firefox, this also occurs in the pdf reader that comes with Ubuntu. If I take a screenshot, the screen will abruptly fix itself before the picture is taken, so I took a picture of it with a camera.

Example 1

Example 2

You can see that in both of these a part of the text repeats itself and is abruptly cut off by the rest of the page. This also occurs in gedit; when I edit a line, sometimes it will not update other lines until I save the document.

I am running Ubuntu 12.04 using nvidia-current for my driver. My video card is a Nvidia Quadro NVS 110m, which I believe is similar to the Nvidia Go 7300. I know there were some issues with compiz and this set of GPUs on the current drivers for 11.10, but I don't know if that has anything to do with this. It occurs on both nvidia-current and nvidia-current-updates.

Thank you for your time!
