Yeah, because it's aliasing with the popup window. Perhaps there's a better algorithm for the blending than what I used. The entire screen is actually rendered at 512-width, that's not a 50/50 split like the textboxes in Secret of Mana 2. It's just that most of the pixels outside of that window are the same on even and odd columns.
The same aliasing may occur on a TV, I'd have to look and see.
EDIT: AWJ, here's Secret of Mana 2. Note the flowers at the bottom.
