Bug Description

After coming out of sleep mode, my keyboard cannot type to the password entry field. When I try to type to the password entry field, the computer sends my input to whatever window I had open before my computer went to sleep. This means that if I type my password and press enter, and the last window I had open was, say, a gchat, I will send my password to the person with whom I was talking.

It seems like this bug only occurs when I had a text entry field selected before putting my computer to sleep.

I'm affected as well, and I have more data on this issue: it only happens with Chrome. I tried several other applications and was not able to reproduce.

Also, it only happens on Unity, other desktop environments are not affected.

I tried 2 different versions of compiz (the latest one and the one before that) and I could reproduce with both, although the behaviour is not exactly the same.

There's no need to suspend. Just locking the screen with Ctrl-Alt-L while having some text selected on the Chrome window usually triggers this bug (it's not always triggered, but something like 1 out of 3 times).
