Comment(by hamish):

 ok so the two grids don't match (your dem map is not on multiples of 20m,
 its grid is offset), and it is being resampled. what does the full r.info
 say? (everything between the Type of map: and Range of data: lines)

 was it a self-made DEM or did you import it from some 3rd party source?
 (ie can you remake it on a cleaner grid without loss?)

 also try "g.region -p rast=dem" before r.topidx so that the region and the
 map perfectly align the map's (offset) grid.
