ubuntu-bug really, really seems to want me to ask this as a question on rather than reporting it as a bug. So I am.

My machine (for which ubuntu-bug has not attached any details for you, but two salient details are that it's an nv graphics card and 2 x 1920 x 1200 heads) takes roughly a half second to change window focus when I move the mouse to a new window. This is very long, enough that I have to think to wait. A reasonable goal in human interface design would be under a tenth of a second.

It's worth noting that I am using sloppy focus mode (focus follows mouse-enter events).

I'm not quite sure how to phrase this as a question, unless the question is "what's the right way to report this as a bug?" or maybe "any suggestions how to tune compiz, and how can we make it so ubuntu users don't have to tune compiz?".

So to get to sloppy focus you opened ccsm, got to "general options", to "Focus & Raise Behaviour", unmarked "Click to Focus" and marked "Auto Raise"? What did you enter for "Auto Raise Delay"? – xubuntix May 10 '12 at 6:25
I have FFM set from before things got complicated (i.e., from metacity days). But running ccsm, I see that auto-raise is unset. Indeed, I don't want it to auto-raise, so this is good. While auto-raise delay is (suspiciously) 500, setting it to 10 doesn't change the focus delay. – jma May 10 '12 at 7:14
I'm having the same problem – Sevenearths Jun 12 '12 at 11:55
Just ran the first suggestion and the delay, has all but gone. down from half a second to about a tenth of a second. I changed the setting from 500 to 1 – SimplySimon Jul 4 '13 at 7:57

That bug is already created at

including a rather exhaustive discussion.
