This is not a new option: it's from 2008. It is somewhat natural for 
things to get slower if Emacs has to do more work - i.e. the completions 
buffer remains visible.

Did the effect of this option get worse over the last week, or did you 
just try setting it to 'always' very recently?

In any case, if you have a good repro for the problem, you can file a 
bug report now.
