Teamviewer doesn't show desktop right - Ubuntu MATE 17.04

I am on Ubuntu MATE 17.04 and I want to use teamviewer to remote my computer from my phone. When I connect to the computer from my phone I can use the “mouse” and the “keyboard” but the only thing I can see is my wallpaper. I mean, I can interact with the computer but I can‘t see anything except of my wallpaper. Any help please?
