I've done the Going Beyond tutorial shown in the videos posted on the XNA team blog, and I noticed I was getting weird artifacts on the spaceship model. I went ahead and did another tutorial, this time using a 2D sprite, and there were also artifacts on the sprite.

The artifact looks like one or more jagged transparent spikes, jutting out from the sides of the model or sprite. They're kinda hard to see, as they are transparent, but they are there. They seem to "roll along," as you move the model or sprite. That's the best way I can put it...they're not static, but seem to pop in and out of view. Also they seem more inclined to show up to the right side of the object being on screen (right side from the viewer's point of view).

Anybody else had/have this problem

What kind of display connection are you using

This sounds like exactly the sort of artifact you get on a lot of TV's because of the way video signals are encoded. Analogue TV signals are particularly bad at dealing with objects on a flat colored background, which is exactly the sort of thing that tends to happen in this sort of simple test app.

I'm using a 21inch Gateway LCD monitor, with the Xbox 360 connected to the monitor via Component Cables. If nobody else has had this problem, might be my monitor, although I've never seen any artifacts like these when playing commercial games (PC and 360) on this monitor.

Commercial games tend not to have objects moving over perfectly flat color backgrounds, though. This sort of signal artifact goes away completely when you have a more complex and varying image.
