Hi Óscar,

Since version 13.1 it is needed to add 'face symbol into 
`whitespace-style' to enable blank face visualization.

So, the proper setting should be:

(setq whitespace-style '(face lines-tail))

 From `whitespace-style' docstring:

     One reason for not visualize spaces via faces (if `face' is not
     included in `whitespace-style') is to use exclusively for
     cleanning up a buffer.  See `whitespace-cleanup' and
     `whitespace-cleanup-region' for documentation.

Best regards,

Vinicius
