I'm sorry, I must have missed the part where the investigation is complete.
I wasn't aware there was enough evidence to blame the behavior on the
intended operation of alpha pulse.

Since this is NEW behavior for most of us who have the issue, something
changed that is causing the behavior.  I have never seen it before 0.22 with
ubuntu 9.10, the behavior didn't change on its own.  It seems a little
premature to say definitively that its NOT a bug.  I'm using the same exact
hardware I was under 0.21-fixes.  I kept the same settings and the same
theme as I had in 0.21.

What happens if the changes for 7525 don't help the behavior reported by
several individuals, what would your response then be?  What else could be
the culprit?  If a developer says this is the ONLY possible way to explain
the extra CPU usage...OK.

If you sure the problem lies with alpha pulse, and that some themes don't
use alpha pulse, I'd be happy to know which ones because EVERY theme I've
tried under 0.22 produce the some high idle cpu usage.

If there is a setting to control this that I am unaware of, please
elaborate.
