Spotify Ubuntu wont go in background

[julianr2403]

Hey

i just installed Spotify on my Ubuntu VM exactly how it is explained here.

But the problem now is that if i try to minimize Spotify it looks like this. And i cant use anything else, because it always is in the forground. So i always have to close it via the terminal and cant listen to any music.

Does anyone have an idea how i can fix that ?

I got Ubuntu 16.04 LTS 64bit.

Thx for ur help.
