While mail reading and composing responses in a tty based mail reader
(mutt/emacs -nw), I'm seeing display glitches every 3-5 minutes. Each
time it's quite minor so it's the sort of thing which is definitely
"blink at the wrong time and you'll miss it".

Being a battery lifetime freak, I'll definitely take the tradeoff, but
given that it occurs even when I'm plugged into AC mains, I could see
some users being annoyed by it, and I could see them wanting to be
able to switch off the feature when they are on AC, if we find a
complete fix.
