Version: 3.16.2-1 I can still reproduce this with gnome-terminal 3.16.2-1, with the added complication that sometimes the spurious size changes don't actually result in the right updates in the programs running in the terminal. Exact steps to reproduce:
1) Open gnome-terminal. 2) Maximize the gnome-terminal window. 3) Open a program that cares about screen size, such as vim. To make it more obvious what vim thinks the screen size is, you may want "set laststatus=2" to create a status line above the command area; however, you can also just type ':' to leave a prompt on the last line. 4) Open a second tab (Ctrl-Shift-T with the default keybindings). 5) In the second tab, increase the font size by a few steps with Ctrl-+. 6) Switch back to the first tab. Notice that the terminal-oriented application in the first tab thinks the screen has gotten smaller, to the width and height of the second tab. This reproduces 100% of the time for me, but in theory it *might* be a race condition with the sending of multiple SIGWINCHes. Nonetheless, the right fix is still to stop resizing the terminal at all.
