I just switched from dmenu to the contrib prompt, only thing to look out for is that the searchPredicate function of the XPConfig doesn't actually seem to do anything.

Setting:

  searchPredicate :: String -> String -> Bool
  searchPredicate = \_ _ -> False

seems to make no difference.

And the default is:

  searchPredicate = isPrefixOf

Patching and recompiling with this patch[1] mentioned here[2] seems to fix the issue.
