Most likely the monitor
Hi,
If KDE and Gnome are both doing this, the most likely culprit is the monitor or the display card, not the visual environment. The monitor communicates the resolution to the display card, which in turn passes information to the applications; if the monitor lies, or one of the pins on the cable is bent, or the card can't detect the signal because of a ROM problem on the card, you can get a false resolution read at the application level and get the result you're describing.
First, check the pins on the monitor to make sure you haven't got one of them bent. If they're all straight, try borrowing a monitor from a friend for a day, hook it up to your machine, and see if the behavior changes. My guess is that it will. If it doesn't, try swapping out the display card (this will take some reconfiguration).
Hope this helps.

Oh, PS: since this started when you downloaded a kernel upgrade, it could easily be related to the display driver. I don't know anything about Ubuntu or Gutsy Gibbon, but I imagine there might be a driver upgrade for your particular display card. Check that before spending any money on a display card.
