Created attachment 1090096 [details] krunner bug After login, krunner dialog is not "composited". The only way to fix it is to restart compositor or restart krunner. It was happening sometimes (very rarely) also in KDE4, however in Plasma 5 it is almost always. It is probably some race condition.
Probably best to send this to bugs.kde.org
