Bug Description

CID: 201303-13027 Dell Inspiron 5535

When rebooting the laptop, sometimes you will see the last window / programs that you opened before you reboot the laptop.
It seems that it doesn't matter if you did close them before rebooting the system or not.
This may raise some security concern.

Steps:
1. Install 12.04.3 + update, boot to desktop
2. Open your home folder
3. Leave it there and reboot

Expected result:
You won't see that home folder shows up during the boot session.

Actual result:
The home folder will flash back after the logo screen,

Not only the file manager, I also saw terminal / Firefox browser / movie player flash back before on this system.
And this won't happen if the proprietary driver was installed.

Video attached, you could forward to 00:55 to see the flash back.
