That's right. That's the situation when I was using Ubuntu 9.04. My screen aspect ratio is 16:10, so while playing videos of 16:9 aspect ratio the top part of the screen is black background thus tearing is not visible. But while playing 16:10 videos the tearing become apparent. Now with Ubuntu 9.10 the tearing part seems to become larger and as a result I got considerable tearing even with 16:9 videos.
