[Ville Herva <v@xxxxxx>]

Just noting that this reproduces (grossly) on my 16.04 Unity, too.
Config: Dell XPS 9530 (4k touch screen) + Samsung 4k external display.
I've tried other external displays and I get the same problem. Happens
with both Nvidia graphics (proprietary) and Intel.

I agree that some of this harder to fix: connecting and disconnecting
displays (be it intentionally or because they power themselves off) -->
not easy to retain the position of the windows when the same monitor
later comes back online. (Could be a different one that is connected,
with a different resolution or layout for example).

Anyhow, windows disappearing outside visible area, being moved from
virtual desktop (workspace) to another, being scaled to 1 pixel width
and moved if they would have fitted into the new screen dimensions,
should not happen, ever.

Further, with 4k laptop display and 4k Samsung monitor, I keep losing
windows even though the monitor isn't being disconnected or shut down.
Just moving between virtual desktops (workspaces) is enough to cause the
windows to move around, switch workspaces and disappear.

Goes without saying that it is quite annoying.

  Windows change Monitor/Desktop after screen lock

Bug description:
  I run a dual monitor configuration, with one portrait and one
  landscape.

  I nearly always have multiple applications open in multiple windows
  across both monitors and all virtual desktops.

  When I lock the screen and then unlock, my application windows will
  move from their original position.

  Sometimes they are in completely random positions;

  Other times they seem to get the monitors confused, and rather than
  being in the top half of the portrait monitor they are on the top half
  of the landscape monitor;

  Sometimes it is only a new desktop, but the monitor position is the
  same;

  Sometimes it is the same desktop, but on the other monitor.

  Description:	Ubuntu 13.10
  Release:	13.10

  What I expect to happen: When I unlock my computer, all the windows
  are in the same position on the same monitor and desktop as I left
  them.

  What actually happens: When I unlock my computer, some or all of the
  windows have been changed to a random position on a random monitor
  and/or desktop.
