Weird distorted line on desktop

If you thought weirdness with regards to this blog was limited to my obsession with grilled cheese sandwiches and the mentioning of Fun Facts which you don't think are terribly fun given your rather stern nature and lack of patience for nonsensical silliness, here's something weird that for once isn't the direct result of my brain.

In the screenshot above can you make out the single pixel line that's been shifted in this particular part of the screen? This is the second time in as many days that my desktop background has been distorted exactly like this.

Back in 1997 my first desktop started exhibiting similar behaviour and we predicted the graphics card was on it's way out. Several weeks later we were proved right. Here's hoping this is just a random software glitch, yeesh!
