You may see a screenshot of the display error I get (openSUSE 13.1, KDE)HERE
I see a weird Desktop thumbnail to the center of the bottom panel where all windows get minimized. You can see it on the screenshot if you zoom on it. It shouldn’t be there.
Can you please advise?
No, that’s not it…just have a look at the panel…between the Dolphin icon (to the left of the picture, to the right of the Chromium icon) and the Audacious icon … in the center of the panel you can see a shadowed “Desktop”. It can’t be seen very clearly, it’s like a shadow.
Yes, this is indeed the desktop’s cashew, i.e. toolbox icon. It depicts the name of the used activity.
Apparently you dragged it below the panel.
Drag it to somewhere else as already suggested.
If the panel hinders you in dragging it, move the panel to a different screen edge temporarily, by clicking on the panel’s toolbox icon (on the extreme right) and click-dragging on “Screen Edge” next to “Height”.
