my 3ds recently acquired what I thought was a dead pixel. its a lot more noticeable in person and can be seen most of the time as it kind of shimmers. the strange thing is if I tilt the screen a few degrees away from me just before the 3D breaks it disappears but its always visible if I tilt towards me. the screen is clean and scratch free. I cant see anything trapped under the screen either. so I took another picture to check the pixels. everything is working but there's that tiny thing the size of half a sub-pixel. surely something that small shouldn't be visible when larger dust particles on the screen cant be seen so wtf is going on? The main reason I ask is because it looks like another one is forming near this one but nothing shows on camera.
