[opensuse-kde] Problem with plasma and dual screen setup

I have setup a system with two monitors and they work well together. But when I want to use the "change user, or logout or shutdown" dialogue, it opens exactly between the screens and there is nothing I can find to force him to present the popup either on the left OR on the right screen. Is there a way to avoid that pop up info windows are opened in between the two screens (in Plasma 5).
