The map image on the dashboard is rendered by constructing an SVG from the bitmap image used on the OLED.
If a horizontal line of dark pixels extends to the right edge (i.e. the rightmost pixel in any row is dark) that line is not rendered.
This bug is latent because the current image does not have any dark regions that extend all the way to the right edge. But it is exposed if the image changed for one that does.
