I couldn't reproduce the problem with unity 3.8.10-0ubuntu2 but now I can with 3.8.12-0ubuntu1. When I enable my external display with the following commands, I see a number of artifacts, presumably from chromium , even though chromium is not in use:

xrandr --output DVI-0 --primary
xrandr --output HDMI-0 --right-of DVI-0 --auto
xrandr --output HDMI-0 --set underscan off

If I drag a window to the external screen, the window is not visible and seems to be just a rectangle filled with artifacts.

If I downgrade unity to the previous release everything is fine and I can use the external screen:
sudo apt-get install unity=3.8.10-0ubuntu2 unity-common=3.8.10-0ubuntu2
