Bug 354546

After disconnecting and then reconnected a screen / LCD display on the reconnected screen the krunner window appears outside of the visible area of it, while on the internal laptop display it still appears at the top of the screen.

Reproducible: Always

Steps to Reproduce:
1. Disconnect the external screen.
2. Reconnect the external screen.
3. Press Alt-F2 while on the external screen

Actual Results:  
Current window looses focus, but I do not see a krunner window sliding out from the top of the screen.

Expected Results:  
Window slides out at the top of the scren

Alt-F2 "killall krunner ; krunner" works around this issue.

This is on top of newest Qt 5.5.1. KDE Frameworks are compiled from git master, but I think the issue has been there before starting compiling it myself. krunner is from Debian plasma-workspace package.
