- Place a sign.
- Type some text on the sign.
- Look at the sign from different distances and angles.
You see the sign, and the lettering that you put on it, and nothing more.
There are extra 1-pixel-wide lines through the sign text. They are the same color as the text. See the attached pictures, which have the glitchy lines circled in red.
I have a GeForce 750 Ti and the glitchy lines show on all but the lowest anti-aliasing setting. At that level the anti-aliasing seems negligible and things are unpleasant to look at.
