Title:
  Windows vanish after suspend/resume

Status in unity package in Ubuntu:
  New

Bug description:
  Similar to comment #4 on bug #1126221 I find windows go missing after
  a suspend/resume. This tends to be one of several Chrome windows that
  are still visible if I alt-tab and hit down with Chrome highlighted,
  but aren't visible if I use super-w.

  This isn't bug #1126221 since I am not adding/removing displays,
  unless there is something happening over the suspend/resume cycle that
  is triggering the same code path.

  I am running a triple head set up on a Radeon HD 6950 with 2GB RAM
  with the radeon driver. Here is the filtered output of xrandr with the
  display layout details:

  Screen 0: minimum 320 x 200, current 5760 x 1440, maximum 16384 x 16384
  DisplayPort-0 connected primary 2560x1440+1600+0 (normal left inverted right x axis y axis) 597mm x 336mm
     2560x1440      60.0*+  143.9    119.9     89.9
  DisplayPort-1 disconnected (normal left inverted right x axis y axis)
  HDMI-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 408mm x 306mm
     1600x1200      60.0*+
  DVI-0 disconnected (normal left inverted right x axis y axis)
  DVI-1 connected 1600x1200+4160+0 (normal left inverted right x axis y axis) 408mm x 306mm
     1600x1200      60.0*+
