This +2432 offset works fine across three monitors:

    xrandr --output DVI-1-2 --pos 2432x0 --auto

    DVI-0 connected 1600x1200+0+0
    DVI-1 connected 1600x1200+1600+0
    DVI-1-2 connected 1600x1200+2432+0

This +2433 offset causes video crap on the first two monitors:

    xrandr --output DVI-1-2 --pos 2433x0 --auto

    DVI-0 connected 1600x1200+0+0
    DVI-1 connected 1600x1200+1600+0
    DVI-1-2 connected 1600x1200+2433+0

As before: using Xorg with twm and a few terminal clients.  No compiz.
