(sometimes) after screensaver is running and password is needed to desactivate the screensaver the password dialog stays visible. Screensaver is off then, dialog as well. Everything works ok but the dialog is not clickable and is positionened in front of all windows. xkill does not work. Reproducible: Sometimes Steps to Reproduce: 1. Set screensaver on, set "ask for password" on (longer then screensaver time) 2. wait 3. enter password Opensuse 12.1, KDE 4.9 (4.9 release), nvidia binary drivers (from Opensuse). Not sure if it's related but powersave is as well not working for the monitors.

Same problem here, only logging out makes it disappear. Re-locking and unlocking does not make it disappear. Very annoying, as the window cannot be moved :) Screenshot attached.
Forgot to add: Running Ubuntu 12.04 with KDE 4.9 through backports repository. (sorry for the multiple posts :)
