3ds xl: 3d mode bright circle

#1nox165Posted 2/7/2013 1:21:34 AM
Ive noticed when playing in 3d mode on my xl that when i move my xl from left or right that the screen gets slightly dimmer.(it almost looks like a wave) Moreover Ive noticed there seems to be a large circle on the top screen and when I move it from left or right the circle moves and parts of the screen go from darker to lighter vice verera.

Is this normal? I'm guessing its necessary for the 3d effect because when i turn it off the 3d mode the whole circle thing goes away.
