I'm using Xbuntu 18.04.1 LTS and when I start the snap applications, they all work fine. But I've noticed only the KDE ones don't have any icons within the applications.
The error I get is:
Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
Running with snap run packagename doesn't produce different results. Can anyone point me in the right direction?
Oh, I've used both --beta and --edge with the same problem.
