As the title says I have some jumping on my DS Lite. I've noticed it twice on Picross and Brainage 2, it's always to one location, going towards the bottom middle of the screen when holding the DS normally. The screen is clean, nothing on the sides. I have a screen protector one (its been on since I got this DS Lite when it first came out.). I can't recreate this at will, it just happens when ever it wants. Any thoughts?
