I'd like to add my belated gratitude. This is the kind of change that 
makes me happier to use Emacs and to continue contributing.

Thanks, Daniel!

1. Open some buffer(s) (the more text, the better) in one or several
windows.

2. (require 'pulse)

3. (pulse-momentary-highlight-one-line (point))

4. Observe, for the duration of highlighting pulse, flickering cursor
and text at random places.

I think it's a rather old problem, I remember seeing it with ECB or just
Semantic at least a year ago.
