           Summary: switching between user accounts unsecure
           Product: kde
           Version: 4.5
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: yester64 at gmx.net


Version:           4.5 (using KDE 4.5.2) 
OS:                Linux

The problem is simple.
If i switch between two user accounts, at switch the previous screen on that
user account will be shown before entering a password.
In the best world it should be blank at all time till after entering the
password so that no one sees what data was entered at that screen.
I noticed this through all KDE versions and i wonder if it is intended or a
bug.
It is just a security concern and not a bug.
Would be nice to have a blank screen at switching between user accounts.
On a note, i use Nvidia drivers NVIDIA 260.19.12

Reproducible: Always

Steps to Reproduce:
It should be the same at any computer. So i am not sure how to reproduce this.
