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.
This is probably bug 183496.
maybe. are the old screen contents visible the entire time while the password is being entered or only a short flash while the dialog is coming up?
