Public bug reported:
I run an external monitor on my laptop in a dual-monitor, extended-
desktop setup. After a recent software update, the contents of the
external screen overlap the internal screen by 14px (see attached
screenshot).
xrandr shows that the external screen is indeed configured to overlap a
bit. Note the total Screen 0 width of 3346px instead of 3360, and the
external display (DVI-I-2) at +1426px instead of +1440px.
steve@steve-laptop:~$ xrandr
Screen 0: minimum 8 x 8, current 3346 x 1200, maximum 8192 x 8192
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
LVDS-0 connected primary 1440x900+0+0 (normal left inverted right x axis y

The problem is 100% reproducible on my system.
