How do you make the unity dash background darker like in natty? Blur effect is too laggy and without the blur, it becomes confusing.
You should try the static blur option, it's set the first time you use the dash in a session for the life of the session, may be less of a performance issue.
If you wish it to look a bit like the no blur used to be, (for all of a couple of wk's) then open the dash over a full screen dark solid color like dark blue or black
Edit: A small workaround till no blur becomes useful & if your current background isn't what you'd like
create a solid color .html - this is for black, a very dark blue works well
Then at session start open the .html in firefox & go
tap the Super button to open dash, tap again to close
