The screensaver seems unable to restore the focus to the application who had focus before the screensaver kicked in. Reproducible: Always Steps to Reproduce: 1. Open an application, for example Konsole. 2. Wait for the screensaver to kick in. 3. Unlock the screensaver. Actual Results: There is no application in focus anymore. Expected Results: Focus to be restored to the application who had focus before the screen saver kicked in. This behavior is observed on Kubuntu 13.04, fully updated at the time of writing.
screensaver is override redirect and gets the focus bypassing them - it has to store and restore it.
I can confirm this bug. I see it on a laptop and desktop, both running Kubuntu 13.04 and KDE 4.10.0.
Also happens when screensaver is activated manually.

There is a lot of "focus losing" in KDE SC 4.10 (on desktop switch, notifications, screensaver, without visible cause) - maybe something in common?
We have a fix for that in Plasma 5.5. If you are still able to reproduce (I'm not), please reopen.
