Public bug reported:

When a window is maximized or made fullscreen, it is first resized to a
slightly bigger size and then made maximized or fullscreen.

This intermittent step shouldn't be there, the window should be resized
to its final size immediately.

To reproduce:

1. Start gnome-terminal, xterm, or any other terminal emulator
2. Launch zsh (or bash <= 4.2, but beware, Ubuntu Trusty ships bash 4.3 which is not good)
3. Execute this command: trap 'stty size' SIGWINCH
4. Verify that upon manual resize the new size indeed immediately appears in the terminal area
5. Make the window maximized (using WM controls) or fullscreen (F11 in gnome-terminal)
6. Notice that there's an intermittent size which is about 2 lines taller than the starting one. E.g. with the default 24x80 size, you might see a 24x80 -> 26x80 -> 58x227 transition instead of the expected 24x80 -> 58x227.

Reproducibility: around 90%, so it's buggy most of the time, but not
always.

Notice that the smaller the font size inside the terminal, the more
terminal rows are added. Looks like the window's inner area temporarily
occupies what previously belonged to WM decoration.

The bug is reproducible with plain Compiz as well as Unity+Compiz, but
not with Gnome-shell or IceWM.
