Description Roman Fietze 2010-02-11 21:39:25 UTC 
Version:            (using KDE 4.3.5)
Installed from:    openSUSE RPMs

When the screen is locked, in my case just black, and somebody moves the pointer or presses the any key, the dialog windows to enter the password is popped up.

Sometimes it can happen, that before the dialog is shown with a black background, that you can see the contents of the desktop for a short moment, maybe for a few hundred milliseconds. This is a tiny security risk, e.g. if somebody knows that and films the screen while doing that.

I can reproduce this almost every time using an openSUSE 11.2 with KDE 4.3.5 on an ATI 780G graphics chipset (R3100), compositing enabled.

I rarely see this as well, but can't reproduce reliably though. Using nvidia-drivers on Gentoo.

Qt: 4.5.3
KDE: 4.3.3 (KDE 4.3.3)

Seems to be dupe of 183496.
