I'm pretty sure this is a sprite rendering issue. The mystery lines appear totally different in Galaxian, and they disappear when sprite rendering is disabled, so they're probably garbage sprites poking into the left side of the screen.
Turns out I was correct, and this one was pretty easy to fix.
A gray line can be seen on the right edge of the screen while playing Mario Bros. This can be seen at all times, even in the menu.
