Multi-monitor: wallpaper is corrupted

[Lorenzo Villani]

Given this set-up:

* Bigger primary screen (1920x1200)
* Smaller secondary screen (1600x900) to the right of primary screen

It seems that the outputs are swapped. I.e.: I get the wallpaper of the smaller screen on the primary output, and the bigger one on the secondary (see attached screenshot).

Thank you for your bug report. Can you click in/use the screen parts that don't have a wallpaper? Do you use nautilus to display the background?

[Lorenzo Villani (lvillani)]

I can't seem to reproduce it on a VirtualBox VM with two monitors using yesterday's live image installed onto the hard drive.

I hope to have the time to update and try again on my real laptop some time this week.

I upgraded my personal laptop and I don't experience the problem anymore. I'm marking this issue as Invalid.
