Wireframe mode affects local map
When you toggle wireframe mode (twf in console), the next time local map is re-rendered (for example if you travel a short distance and the cells get reloaded), the wireframe mode corrupts the re-rendered cells, while the rest of the map stays the same (see the picture). This bug doesn't happen in vanilla.

Looks like the orthographic map camera is rendering new snapshots in wireframe mode if it's enabled. The parts of the map that stay the same seem to be parts that haven't been flagged for re-render. If you move far enough away and then go back, it'll be re-rendered in whatever rendering mode you're in.
