it turns out, you have to set the whole list, not just one. The above
will basically make it not display any glyphs to tabs and spaces.

I spent several hours looking into this, here's the solution:

(setq whitespace-display-mappings
 '(
   (space-mark 32 [183] [46]) ; normal space
   (space-mark 160 [164] [95])
   (space-mark 2208 [2212] [95])
   (space-mark 2336 [2340] [95])
   (space-mark 3616 [3620] [95])
   (space-mark 3872 [3876] [95])
   (newline-mark 10 [182 10]) ; newlne
   (tab-mark 9 [9655 9] [92 9]) ; tab
))
