Oh no, that's how the sickness starts... ;) You're playing a really fun game and all you can think is "the bottom left corner flickers more than the rest of the screen" or something similar.

I never thought much about H and V linearity until I noticed something odd while playing Shinobi. I think it's the 2nd or 3rd stage (not a hardcore Shinobi fan so I don't know from memory) that has a grid or cross hatched pattern in the background. As it scrolled I noticed that the squares got smaller and bigger depending where they were on the screen. It's also easy to spot vertical linearity problems when you boot up Street Fighter 2 (when the high rise building scrolls down the screen).

I don't know if you can ever get linearity technically perfect but there's definitely a sliding scale between "best" and "worse".
