Comment 3 for bug 1397119

It is also annoying for apps that put the terminal into a special mode (for curses, and such).

Example: vi

When coming back to the terminal, vi gets stopped automatically, and terminal (stty) settings are restored by bash to their default mode. When foregrounding vi again with fg, it doesn't restore the stty settings that it needs, and from thereon its output is all messed up.

Happens not only if you switch to another application or scope, but also when locking the screen.

This is a useability nightmare when using via as a notepad during shopping, and putting the phone into your pockets between jotting down notes at various places.
