Comment 5 for bug 124315

Same here. I noticed this problem with Gnome Volume Control.
I always leave it opened, in the bottom left corner of the first desktop/workspace, but when I power up the computer, it always opens up in the top left corner, not bottom left. It does remember its window dimensions, though.

One thing I noticed, if that helps, is that as far as I can witness, this only happens when logging in for the first time (just after the machine has been powered up), but once logged in, if I log-out then back in again, the volume control window is restored properly.

Hope that helps...
