HI guys,

When running KDE on a arch - linux distro like manjaro, endeaovour, etc. There are certain applications that do not respond in normal dialog boxes. One of these application is virtualbox. Does anybody has a clue what's the matter and why I seem the only one in this world with this problem?

When I work with arch and virtualbox just in command line everything is working fine. It is just the GUI that is not working. Running another desktop like xfce on the same os is also working.

Any help and hint will be greatly appreciated.
