 This ticket is just related to `d.mon` (when you start a new monitor).

 `map.png` contains both raster and vector map, which is OK.

 `map.png`. So, I'm not sure

 I am not sure what you are referring to. Anyway `d.mon out=` checks if the
 file exists. If `--overwrite` is given than the file is overwritten. If
 you use `--overwrite` together with `-u` flag that the file is open
 'update' mode, ie. new data are rendered on the top of the existing file.

 This ticket is related to the fact that `d.mon` behaves differently when
 launched without `output` option (when using default display driver output
 file).
