Package: gnome-shell
Version: 3.2.2.1-2
Severity: normal
Dear Maintainer,
I used to work by using dual monitor, and using DisplayPort to connect my
external monitor.
when booting complete, I connect external monitor by DisplayPort,
gnome-shell use the external monitor for extra workspace automatically,
that works good.
Once I use xrandr to set to output for screens, the wallpaper might be
fragmented and each items on desktop will disappear.
this is the way I use xrandr, it turn off LCD of laptop, and set the
external monitor to 1920x1080.
$ xrandr --verbose --output DP1 --primary --mode 1920x1080 --output
LVDS1 --off --output HDMI1 --off --output VGA1 --off
this is the screenshot of result.

this is the screenshot when I trigger the hot-corner to see the dash, it
looks correctly.

In the transition from Seeing-Workspace to Seeing-Dash by triggering
hot-corner, I could see the correct wallpaper and disappeared items in very
short time.
Moreover, not only above xrandr command cause the problem, but also the
command to turn off external monitor.
$ xrandr --verbose --output LVDS1 --primary --mode 1366x768 --output
HDMI1 --off --output VGA1 --off --output DP1 --off
Configuration:
External monitor: Dell U2311H
Laptop: Lenovo thinkpad x220
connect to external monitor via DisplayPort
