Bug#779617: Full-screen game messes up Xinerama setup

[Daniel Richard G.]

Package: assaultcube
Version: 1.1.0.4+dfsg2-1

I run a Debian jessie system with Xfce and a desktop that spans two
monitors; e.g.

    [ ONE ] [ TWO ]

I start AssaultCube. It does not recognize the Xinerama config, and
displays the same full-screen presentation on each monitor:

    [ AC  ] [ AC  ]

Fair enough; that's not always going to work.

When I exit the game, however, I see that my desktop layout has reverted
to the same arrangement:

    [ ONE ] [ ONE ]

I fix this by running "xrandr --output HDMI2 --right-of HDMI1" (and
moving some windows back to the second desktop), but haven't needed to
touch that command in a loooong time. AssaultCube should know better
than to futz up the display layout configuration like that.
