Isn't that a window configuration? I don't get it.

I don't know what mpc.el is, so the statements has no meaning.

The most obvious thing is flickering. When the user clicks on the tab Gtk+
switches tab, there is nothing you can do about that. Depending on what was
drawn in that widget previously, something else is shown than what was shown
in the old wiindows before. Then a callback is made. From here we can
generate a Lisp event. Then the event goes to some elisp defun Then the
window confiuration is extracted and applied. Then redisplay happens. This
takes time and looks bad, unless you have a fast machine.
You guys seem to think that tabs are just extra buttons to be pressed. In
Gtk+ they are not. When you press on a tab an whole new Gtk widget (with
associated X window) covering the whole frame is switched in. So the old
contents is not shown. Doing window configuration switch as fast as we can
helps, but it still isn't good. Workable, but not good.
Add saving of the old configuration to this and more time passes before a
redsplay.
Then there is the race condition. Say we restore window configurations in
elisp. But from the time Gtk+ does the switch until the new window
configuration is in place, the old one is in Emacs idea of what is on the
screen, but as I said earlier, it isn't what is really on screen. So
redisplay may happen, based on the old configuration, making the flicker even
more annoying.
