Screensaver leaks password key-presses through to applications

[Redders]

This is similar to the bug described in:

https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1306970

But as that is marked fixed, perhaps this is something different.

A few times, I have been unable to enter my password until I had clicked in the top right corner, and back into the password box.
I hadn't suspected anything serious, until today when I tried to log in, and eventually got in, seeing that my password had been set to my web browser.

In addition, I've also had instances where I've had to enter the password twice, and instances when I've come to the computer and it appeared not to be locked, until I moved the mouse, and the lock screen displayed.

Status changed to 'Confirmed' because the bug affects multiple users.

This may, or may not be linked, but this may in some way be linked to VirtualBox, as at the time I experienced the issue, I was using VirtualBox a lot, but recently I haven't been using VirtualBox with a head so much, and I haven't noticed the issue.

The machine was rebooted a little over a day ago. I'm pretty certain it had the update well before then.

Apologies. I was trying to respond to a different bug.

Mh, virtualbox might be somewhat related to this because it creates a grab... Lockscreen shouldn't be shown at all in this case BTW.

Can you still reproduce this issue?

[Andrea Azzarone (azzar1)]

Please confirm that you can still reproduce this bug.

Not nominating for X until we are sure this can be reproduced.
