Comment 73 for bug 278471

Hi Everybody: I think there is a solution without killing krunner. When I killed krunner it did stop flickering, but on my machine there is also another way: just uncheck the "start automatically" box for the screen saver in the Desktop Settings (available via System Settings).

The flickering is gone and I can use krunner, yay!

For a screen saver, I use xscreensaver (I put it in an Autostart script).
