Title:
desktop or other past screen contents visible before lockscreen on
resume

Status in Unity 7.2 series:

Bug description:
[Impact]
On resume from suspend, screen contents are displayed for a brief time
(perhaps 0.5 to 1 sec) before the lock dialog appears.
These screen contents are not always the desktop or open application
beneath the lock screen. On at least one occasion, the screen showed
content from a full-screen video that had been playing in Firefox some
time before the computer had been suspended: neither the video nor its
underlying tab were open anymore, so the image(s) was likely part of a
buffer somewhere. (Needless to say, if the wrong full-screen video had
been watched, depending on the setting, this could be a quite serious
issue for some users).
[Test Case]
Suspend and resume the computer (closing the lid or using the session
indicator). Since this problem involves a race condition, it is not
reliably reproducable at will.
[Regression Potential]
This fix unmaps windows when a suspend or shutdown event occurs: it
is possible that the window(s) do not get remapped when a wake event
occurs, or the wake even does not get propagated. This does not
appear to occur in practice.
[Other Info]
The Ubuntu 14.04 LTS SRU was cherry-picked from upstream Unity where
it has been released in the Ubuntu "Vivid Vervet" development release
for a couple of months with no apparent regressions.
