D18377: Update blur to be more natural

rooty added a comment.


  hey guys so i don't understand any of what's being talked about here but i've noticed that with this latest patch, latte-dock turns very very dark, could this be a bug in latte-dock unrelated to this patch?

  (the opacity is set to 50%)
  
  konsole's blur looks a lot better though, and blur elsewhere in plasma looks either the same or a lot better
