Joseph, the bug is still there in latest 3.4:
Linux kelly 3.4.0-030400rc3-generic #201204152235 SMP Mon Apr 16 02:36:13 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
I found that sometimes when I close lid without locking the screen, the latest picture stays on a screen and mouse cursor is shown, but I cannot press anything on the screen.
