This appears to be a regression in 14.10 sometime in September 2014.
The behavior appears similar to this bug from 2011: https://bugs.launchpad.net/unity-2d/+bug/830348
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 a 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).

I have not exhaustively tested conditions in which this appears. However, just now, the bug did not appear when keeping the lid open, suspending, and then resuming with the power button. But when suspending from menu, closing the lid, then opening the lid and moving the mouse, the screen displayed contents before showing the lock dialog.

[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. |
