Title:
notify-osd busy polling consumes CPU and drains battery
To manage notifications about this bug go to:
Instead of polling all the time, wouldn't it be much more efficient to
have something like this?
- embed the notification bubble window in a larger transparent XWindow which
provides an invisible frame in which the fading happens
- subscribe to focus in/out events (GDK_ENTER_NOTIFY) in both

To manage notifications about this
Ah, seems I was slightly misled. As far as I can see, all five (or so)
timeout handlers are cleaned up properly, i. e. notify-osd is quiet when
there is no bubble and the system is idle.
However, notify-osd needlessly keeps waking up for each X event (mouse,
keyboard, screen, etc.), which is what
I can confirm that stracing notify-osd when not showing any bubbles
yields a neverending stream of poll() and read() calls, so it seems the
removal of the timeouts doesn't work properly?

I don't think we need anything clever here - the obvious question is:
Why do we run these handlers when not rendering bubbles? NOSD should
just uninstall the timeouts when the queue becomes empty.

Looking at bubble.c it does appear to be the case that timeouts are
removed when the Bubble instances are disposed. So either we only have
a power surge when bubbles are on screen (which is probably not a big
issue then), or the Bubble objects are leaked, keeping the timeouts
going?
