Comment 19 for bug 1311403

I'm new to the Ubuntu community, however I just experienced this behavior from Unity. However in my case I didn't have to fully suspend the computer.
In my case Ubuntu put my monitor into power save mode.
When I moved my mouse to wake my screen back up I was at the lock screen, clicked into the password box (currsor appeared) and began to type, nothing was being entered. I clicked the control icon in the top right then back into the password entry field, it began to recognize characters and let me back into my session.
Once I was in I saw it had put my password into my last clicked on text entry box (a Facebook chat). Definitely a security risk.
The other applications I had open were terminal (ssh'd into a server), document viewer (pdf), & had an audio stream playing in a flash based player.
I've only been using Ubuntu for about a week and this is the first time I experienced this issue.
The only recent (past couple days) I made was installing flash player.
Just sharing my experience in case it's of any help.
