My MATE desktop 1.16.2 has stopped redrawing the background. The effect being that when I move a window, the locations where the desktop background would normally be shown, now shows smeared out samples of the window I am moving.

My desktop background was originally set to show Cosmos slide show, selected from the Appearance Preferences menu.

When I mouse-click right-button on the desktop area, no menu appear. Normally it would show a menu with a Change Desktop Background item.

On the top MATE menu bar, select System > About MATE. You should get a pop-up window showing MATE version number. Press Close. Desktop background should now work again, and be black.
