If you move the "cog" icon from the top left corner of the desktop you'll notice the words "default" right next to it appears.
The issue comes when you try to place it anywhere else on the desktop, it will start showing odd behavior.

The word "default" will not hide as it happens when you place it back on the top left corner. 
The word "default" appears top vertically when moved to the left side of the desktop. On bottom on the right side.
You cant place it on the center of the desktop or near it, it will snap to either top/bottom/right/left side of the desktop. (May be this is ok, not sure.)
If you want to place it on the top right corner, like me, and you click over any character of the word "default" and drag it there, an endless auto-hide animation loop will trigger.
Do the same but instead of click and drag over the "cog". Now it will not auto-hide, you'll need to click over it for it to happen, but when you click it again it will pop to the right again.....
