I made some tests but not on real hardware. I used VirtualBox.
I didn't have any of the problems described in this bug report. I checked with a couple of windowed programs and then with Firefox in fullscreen and the last test was with Evince in fullscreen. When I resumed the only thing that displayed was lockscreen (no view of the desktop or it's past contents).
Adam in his comment didn't specify the version of Unity and I assume he isn't using the version from -proposed.
