Turn off Application Dock??

[MrGlaurung]

All of a sudden I got a very annoying application dock showing on my screen (it's to the left in the screenshots).

I have never seen/heard about it before and I dislike it very much.

Can I turn it off?
If yes - pretty please with sugar on top - tell me how!!!

Did you check in your launcher settings?
