To get the "bug", you need to be using DVI (digital) inputs to the LCD screen. Also, you need to have the refresh set at a speed higher than 60Hz.
The "jaggies" (which are impossible to miss since they make the whole screen fuzzy) then occurs if you try to watch a video at fullscreen. I think if you read through the original thread you will get a sense of what works and what doesn't.
Unfortunately, I don't have a screenshot available since I am not near my Linux pc now
