Hi Martin,
I’m wondering how can you see the balloons without any further action?
I guess you clicked too many times on the version info, isn’t it?
This is just a debug mode for me as developer in case when people have problems with their sessions.
To disables that ones, just go to about section and click seven times on the version. After this the balloons are gone and you should be back to normal mode.
Does it help you?
best Matthias
