I did some preliminary examination of the nautilus source code from the
Trusty repo. There is a helper object which is used to change the
desktop background, in libnautilus-private/nautilus-desktop-backround.c
(this file was actually removed in upstream:
https://git.gnome.org/browse/nautilus/commit/?id=372c60d3f8590280df23f457a67652adec369697)

The actual scaling and drawing of the desktop background is done in
gnome-bg.c in the libgnome-desktop package. If/when I get the chance,
I'll try to play around with it and see if I figure it out.

Title:
  Multiple monitors with different orientation leads to stretched
  wallpaper when waking up.

Status in nautilus package in Ubuntu:
  Confirmed

Bug description:
  I have three monitors all hooked up to a Radeon 6950, using fglrx.
  One of the monitors is in portrait orientation and is a 1680x1050
  monitor while the two monitors in landscape are 1920x1200 monitors.

  When I first select a wallpaper (say a wallpaper that is 1920x1200),
  it does the Right Thing.  That is, the two landscape monitors show the
  wallpaper as you'd expect to see a 1920x1200 image on a 1920x1200
  image display.  The portrait monitor shows a slightly scaled portrait
  aspect rectangle out of the center of that wallpaper.

  When I leave my computer for some amount of time the wallpaper on the
  two landscape monitors is zoomed by what I assume to be the same
  percentage as the wallpaper on the portrait monitor.

  I say "for some amount of time" because if I set "Turn screen off when
  inactive for:" to 1 minute and "Lock screen after:" to 1 minute and
  then wake them up and unlock after a few minutes the problem hasn't
  manifested itself, but _every_ time I'm away from the computer for
  longer periods of time the issue has manifested.

  To fix, I merely change the wallpaper to another wallpaper and then
  back again.  At this point the wallpaper displays correctly.

  See the attached image for screenshots of the issue.
